I have a Spider IV 75, circa 2012. It was unused for some time, then in trying it out, no response at all other than power on, display working correctly, white noise and crackle, and very very loud bang/cracks when I try to connect a jack. I removed the top amp section, cleaned all the moving parts I could find, put jacks with contact cleaner in and out of any sockets. The white noise and crackle has reduced a lot, but the 'big bangs' are still there, with no sound going through. Connecting a device through the rear mini-jack is no problem, with no background noise, and output level controlled happily by volume. So speaker and basic amplification is fine. 4 questions:- 1) Anybody recognise the issue and can point me to the likely culprit? 2) Any recommendations to sites online to buy spares of boards etc? I'm based in SE Spain. 3) What's the likelihood of an experienced amp fixer (I am not one) being able to fault find and get parts? 4) Failing all else, any recommendations for price for a spares/repairs posting on eBay Spain? As I said, line in, headphone, speaker and amp and display all seems to be working happily. Thanks for any help. (PS I also have a Amplifi 150 that only lights up the ABCD voices dimly, but other than that totally unresponsive. Power supply or System board? Also cleaned it down, no luck)

Title says: Make FX loop great again. They should! Here is how: Having experiented a bit with the FX loop and trying a lot of things. There is so much wrong with it. You wanna have a FXloop for on of your Gainpedals infront of your digital amp? Noise You wanna have a OD Pedal before your digital Distortion Pedal which also is in front of your digital Amp? Even more Noise You wanna extend your HX (Stomp or Effekts probally) with hardware Pedals cause your preset its allready packed full? wakwaaaak Your FXloop also requiers Blocks which takes space from your overall preset. Sadly, if you think you can "upgrade" the capabilitys of your effects of stomp your mistaken. Idk what it is with Send/return or Loop blocks. pretty sure it wont take much DSP away from anything. We have come so far. Since Update 3.0 we enjoy 8 instead of 6 Block in HX Stomp and Effects. Fix to get more out of the HX: Whouldnt it be great to get Send/Return or Loop Blocks there own sort of thing? Like the Signal Split. We can allready to it, it takes no block. I whould love to see Line6 implement 1 free FXLoop or 1 free set of Send/Return in non Helix hardware with limited Blocks. Just like the Signal Split. --- And that noise.... Its pretty much unusable if you plan on using an Amp within HX and use Hardware OD oder SD. Digital OD and SD are fine. And thats really a shame. Not even the best Gate Pedal with 4cm will help you with that. Since it only takes to block with no hardware signal chain attached to throw white noise at you like nothing else. Can we talk also about FXLoop in Stereo. If you plan on using the Stereo Loop with a Splitter cable to get FX L and R at the same time... yea, you get that. But one Signal chain will be left, the other right. Giving terrible phasing problems. Pretty much unusable that way. Fix for phasing?: Why is it that you dont have a option to make both inputs Mono instead of one R one L stereo. So you can have both of your signalchains but the just produce mono sound. Ofc you want that stereo stuff for delays or something like that. But the raw signal with OD. we dont need stereo for that. Point 1 and 2 combined "Fix": Imagin not having a Send/Return/Loop Right and Left in the first place. Why not having just Send/Return/Loop and let us choose L/R in the setting of the block. That whould mean if you want to create a Preset with 2 different loops, Left and right, you can change them via Snapshot or Button. you have your X Pedal active and wanna switch snapshots and get your X Pedal off the Signalchain and add your Y Pedal. If its an option to select which Channel you wanna have its an instand win. Leave the Trials in peace and you can have 2 signal chains for the price of one. Overall i love my Stomp. But im just so disapointed of the FXloop. Its just a hassle and you litterly gain nothing from it. You actually loose more then you gain, since you cant adress normal pedals via Midi and can only have 1 loop at a time despite having the capabilitys for having 2. I know this phasing issue is discussed for years. And i know that nobody from Line6 will even read this thread. but damn i wish they whould cause i feel like after making such great upgrades to the software, this whould turn the HX from 10 to 11. If you have workarrounds for that. feel free to tell me. I have my setup working now, but again, i have to delete Blocks to get Room for FXloop which doesnt really do a lot. I simply cannot have stacks ODs or SD in a chain even with a Gate cause of the all present whitenoise which comes even when you dont have a pedal plugged in. And i cant use the Stereo send and L/R return to its fullest cause of the phasing and Stereo issues. PS: All that stuff whould also make extremly good sense considering the new ishly HX One. If you want to expand HX Stomp or Effects via HX One, you encounter the exact problems. Noise - FXloop blocks ... Fixing them or just adjusting the function of FXloops/Send/Return means HX One becomes actually more viable as an upgrade option. listen to me Line6 :P

I just got an HX Stomp, but I'm having an odd noise issue with it. I'm running a HydraSynth into it, and there's a weird digital-sounding, scratchy noise, even when the pedal is bypassed. I made a brief recording of it, which you can find here (I tried to attach it, but that doesn't seem to work). I made this straight from the pedal over USB. The signal path is Hydra into the HX Stomp, output into my monitors. I've disconnected the USB cable to see if that's causing the issue, but there is no difference. The synth output is perfectly clean, I tested it by running it into a Teenage Engineering TX-6 (which also means it went from its balanced output into an unbalanced input, just like on the Stomp, so that's not the issue either). Running the synth straight into my monitors also works just fine, no noise issues. When I turn off the pedal, the noise goes away (which is to be expected, I guess). What's really weird to me is that I get this noise even when the pedal is bypassed (using the analog bypass option). I guess the signal still passes through the volume control at least, though. The pedal is brand new, and I've updated it to 3.71. Any idea what could be causing this?

Hi, I'm connecting the Pod Go with the orginal power supply. As soon as connected to speaker, an unacceptable hum is heard when turning up the volume. The noise is there even nothing is connected to the pedal, and even the pedal is off. I tried different cables and the problem still occurs. Please advise. Cheers

Hi gents! I just finished wiring up my pedalboard and I can't solve this issue. My signal path goes like this I go with a 4 cable method: Guitar -> Hx Stomp Input -> Splitter cable -> [R side goes to AMP From AMP SEND -> Return R] [L side goes to switcher -> Return L] -> from HX OUTPUT -> Return AMP. Now my problem is when both loops are engaged and some outboard pedals are on I get a high pitch noise like a feedback. I cannot get where is the problem. Can you help me?

Hi there ! Trying to use the HX Effect with my 2-channels amp. No problem with clean channel. No problem when using line6 HX effects internal distortion or OD amazing tone When I engage my amp lead channel, HX Effect cause some noise problems with the amp. - I know that gain must generate some noise - My amp is usually quiet - This is a groove tube amp with high gain capacity but I keep gain relatively low - Other setting WITHOUT HX effect with pedal in front that are not true bypass don't generate this noise - This noise is NOT 50hz hum ground-loop noise, single pups noise, but more shhhhhhhh kind of noise (noise of snake not happy with modern jazz) - When testing, I mute all the effects - The unit is plugged in front (I plan to use the FX loop when this issue is solved) - I compare bypass and engaged tone, Huge difference with noise when HX effect is in line - All the input/ouput are set to instrument level. Is there anybody having the same issue ? Do you think this is the classical noisy HF effects syndrome ?

Hello! I want to use HX Stomp XL as audio interface. My problem is that simple audio playback and recording are as noisy as changing frequencies between radio stations. The sound is unrecognisable. Sound file attached. Of course, I installed HX Edit and the firmware, everything is the latest version. The pedal works perfectly with the bass, I can also work properly in HX Edit. I did reset Stomp to factory settings. The problem persists. There are no special settings in the Audio MIDI setup. 48000khz and Steam 1. (image attached below) I also checked the cables. Attached the Ableton settings image below. Focusrite Scarlett 4i4 was previously installed on the Macbook, which works flawlessly (and all other audio interfaces too). Could this be interfering with Stomp? OS and software versions: - macOS Sonoma 14.3.1 - HX Stomp XL Firmware 3.71.0 - HX Edit 3.70 - Line 6 Helix Driver2 Version 1.5.0 - DAW: Ableton Live 11 lite version 11.3.21 I read the HX Stomp maunal, asked Google, Youtube, AI to review the docs and asked him, but I couldn't find the solution. What did I miss? Any ideas? I tried it on Dell Inspiron with Windwos 10, that one is a bit older notebook. Focusrite was also installed before, tried with it, then uninstalled it as its possible. But the results were the same. Audio MIDI Setup Ableton settings xs-stomp-xl-rec-sound.mp3

Ok there are a bunch of posts on this topic but I didn't find any with pictures, or any that were specifically for a helix LT model, so following the instructions from those posts without being able to see what I was getting into was a bit scary. If you're a smooth-brained half-wit like me and you need pictures (and you have an LT model). Here you go. Here's the summary of what you're going to do. Take the back off. Loosen the expression pedal bolt. Apply some lube to the spacers that the pedal pivots with. Put the back back on and re-tighten the pedal bolt. 1. Take the back off. To do this, you need to remove almost (see exception below) every single screw you see on the back and sides. You'll need a small phillips screwdriver and a small hex/allen wrench (sorry I don't know what size the one I used is). EXCEPTIONS DO NOT REMOVE the 10 screws around the XLR left / right outputs, Variax / Digital Out ports, and power cord port. You don't need to remove the two screws directly underneath the pedal. I zoomed in on them in one of the attached pics. It's ok if you do remove them, but know that they hold a plastic support piece in place for the pedal to rest on inside. When you remove those screws that plastic piece will come loose and you'll hear it rattle around the inside and then think you've ruined your wonderful line 6 helix. You haven't. It will just scare the crap out of you and then you'll figure out later (like I did) that it reattaches really easily. 2. Loosen (don't remove) the tension bolt that the expression pedal rocks on. You'll need a 10mm hex/allen wrench for this. I made about 3 complete turns to loosen it to the point where the pedal rocks forwards and backwards pretty loosely. Three may be too many turns for yours - keep an eye on the nut at the end of the bolt and don't let the bolt come out of the nut. You're basically loosening it just enough so some lube can work it's way in between the white spacers/bushings and the metal where the pedal attaches. Ok so at this point, you've got the back off. The tension bolt is loose and you can see the two white spacers/bushings at each end of the expression pedal tension bolt. 3. Apply a very small amount of lube to the top of the spacers right up against where they touch the metal bracket/braces. By "a very small amount" I mean try to use as little as possible. If you use something that drips, clean up the drips. But try not to apply any amount close to an amount that would drip or spread to another area of the board. Apply some lube and rock the pedal back and forth. Do this until you feel like the lube has probably worked its way in some. Re-tighten the tension bolt. Rock the pedal. Still hear the squeak? Loosen it again and apply more lube. Follow this process until you are squeak free. Worked for me on the first go. What kind of lube should you use? I have no idea. Would be nice if someone from Line 6 could answer that in the comments. Other posts on this topic reference many lube suggestions including chapstick (of any flavor), white lithium grease, bike chain oil, silicon lube, this teflon dry lube, and others. I used a really thin bike chain lube called "Dumonde Tech Original". Don't use WD40 - it can be corrosive. Don't spray anything. Whatever you use, apply it to a small q-tip or a thin piece of plastic as an applicator. 4. Put it all back together. If you did end up removing those two screws under the pedal that I referenced above, reattach that plastic piece to the back first. Then put the back back on and screw all the screws back in. Be careful not to tighten too much and strip the screw holes. Just snug, hand tight. That's it. You did it. You're officially a hero now. No one will care that you fixed your squeak, let alone on your own, but don't let that stop you. Rock on with your invisible hero cape. You earned it.

Hey everyone. I've been an UX 2 user for almost 7 years and never had a problem, until now. I bought a new computer with an I7 13700, 32 Gb ram and etc... a high-end system. 1st thing I did was installing my UX 2 and podfarm 2. I got the guitar and there is just a buzzing, piercing noise coming from the speakers and I am desperate since I have no idea how to get it sorted and what is the conflict. Tried also with STL to check if it was Pod farm but nah, same thing. Terrible noise. I've checked the settings over and over but can't figure what is wrong. Downloaded ASIO also, just in case but nothing, same story. With my old computer (almost 9 years old) everything worked perfectly. With this new one there must be something I am missing, I guess/hope. Any idea what could it be? This is just so frustrating. Thanks

Hi, I have a preset with snapshots using 1 amp (the cartographer which is great). Obviously because of using snapshots I have different parameters on the amp per snapshots. When I switch from one snapshot to another there is a loud pop noise. Is there a way to avoid that noise. I tried to use an eq pedal to regulate volume and keep the volume on the amp channel equal but this did not solve the issue. I also tried to put the amp in another path but this did not help neither.

Hi, I've just got a new Spider V 20 MkII as an upgrade to my Spider III. I was surprised and disappointed to hear the loud buzzing and high-pitched whine coming from the amp on all settings except clean. My Spider III is completely silent on all modes, including INSANE. The Spider V is pretty much unusable because of the noise emitted when there is no significant input from a guitar. I have tried changing guitars, changing instrument cables, using different power sockets, moving to different rooms, but nothing seems to improve it. I can remove a lot of the noise using the Spider Remote noise gate and adjusting gains, but I don't see why that should be necessary with out of the box, factory preset tones. Is there something wrong with my Spider V amp or is this just something this amp does? Any help in getting rid of this unwanted buzz and whine is appreciated. Thanks

https://youtube.com/shorts/RelV779FIjQ After I moved to this new apartment, it did not have this noise right away but it started to get this weird hum/hiss/buzz sound. It sounds a lot worse with the headphones (because it is right next to you ear). It is worse when I using single coil guitars. Thinking it could be ground loop, I used the power conditioner from Furhman? still had that same noise. I took it to a shop and people there said there is no issue. FS1 is boost, FS2 is overdrive, FS4 was compression pedal. When I unplug the guitar, there is no noise. Using the position 2 and 4 from start cuts the noise off but when you play that noise can be heard in the back and leaves the trails of the noise. I tried doing everything, plugging just the pedal in the power, trying it in the different room etc. Nothing seems to work so far. I will be taking it to different house maybe in few weeks but other than that I have no idea what is causing this. What could be the issue?

Hello there. I'm a UX2 user like 5 years, which i've been gifted by my uncle in USA. Once, i had not any problems, while i was using Windows 7 i suppose. Then in time, some problems started to occur. Biggest one was -and still is- that, all of a sudden sound is gone and i don't have any option but to restart my computer. Either playing a game or watching a video, listening to music, all of a sudden, bam! Sound is gone and nothing helps but a restart! And it also randomly happens again after a restart as well. I started to have this problem in Windows 7, had in 8 and now in 10 it still happens. I did not change any computer part since then (cpu, mobo etc.) Besides, i've not got a second problem, which freaks me out often. As before, during any playback, a loud "white noise-ish" distort occurs for a second or two, then playback continues. This happens quite randomly, sometimes twice in 10 seconds, sometimes once, sometimes never. I've tried every driver i can, the oldest and the newest ones, tried changing the buffer sizes, buffer lengths, depths etc. What's more interesting is, this problems do not happen for two or three weeks, and the week after, it's an absolute nightmare! It's like, as if it has something to do with the days of the months! I do not overclock, my system is all stable and not overheated during even the hardest gaming sessions. I'm quite fed up with this problem. One day, i'll break the hell out of this device and post the images as an ultimate solution for the people who have such problems as well.. Please, i beg you; please help me!

Hello! I've had a Line 6 Toneport UX2 for a couple of years now. Recently I got a new desktop PC running windows 10. When i connect my toneport all I can hear coming from the outputs and the phones output is a loud hissing noise. Drivers are all up to date, line 6 monkey shows me all green ticks, asio drivers are all ok. the input vu-meter is always at maximum even though nothing is connected to it. no input signal, no output sound (except for the loud hiss.) Running it in a usb 2.0 on the motherboard (so no usb dongle or something like that). Tried it with all ports, a couple of different usb cables. I've also tried seeing if my PC's output voltage was the problem but everything is ok, no overclocking done. I'm running out of ideas. Could anyone help me with this?

Hi, I have a PODxt Pro, I recently started getting terrible EMI Interference noise (its not the 60 hz hum) on all outputs Digital. and all analog outs ie Balanced, unbalanced, headphones....... Its not guitars, cables, output devices, or external surrounding electrical devices........... when I was trouble shooting noise source ie... ground loops, firmware, surrounding electrical devices,.... all of which I think I have ruled out. I have one question, I never noticed that the internal POD power transformed hummed, even though that is not what I hear from outputs. Can anyone tell me if this is normal with the POD xt Pro power transformer to hear the 60 hz hum when device is powered on with no inputs or outputs connected? Thank for all replies in advance, Jeff

I love using the helix with my real tube amp. I can use the real amp-sounds and just effects and/or the preamp modulation from helix and a real power amp kicking a real cab. Now, I would reaaaally love to have the helix connected to my DAW at the same time so I could also record and reamp the signals but plugging the USB between my helix and my mac causes all the speakers go justinbieberbangingcyborgbritneyspearsbrmmmmmmmm : C I haven't had this kind of problem with any other gear in my home studio. Any ideas? I could just use the analogue connections back and forth between my mixer but would love to skip all the A/D/A-conversions...

Hello Line 6 community, I am using an HX Stomp as part of a bigger pedalboard recently and have been able to play without issue at home. However, I did my first outdoor gig with it and experienced what sounded like a ground loop noise through the PA system when I was hooked up to the PA and pedal board. I bypassed the helix, sound was gone. I used only helix, sound was gone. Both power supplies for pedals and helix were on the same power strip. I believe it is ground because the noise is consistent regardless of the output of the HX (I turned the volume all the way down) Anyone have any clues? On a side note, I always get a hum when I use analog bypass. I am wondering if there may be something specifically faulty with my unit. Thanks in advance

Hi guys, does anybody have problems with high pitched background noise since the latest update ?

Hi, I am a new Helix user. Love the power. I have researched this topic, but not found any resolution in the forums or online. So, please forgive me if this was solved. I am plugging the XLR out of the Helix into the PA Mixer. No inputs on the Helix. New Patch with nothing in it. The main volume is at zero. The helix has an steady white noise hiss that is high enough to make the unit unusable. This happens on all outs. The XLR outs are set to MIC. If I unplug the XLR cable from the helix the noise goes away. If I plug a microphone into that cable directly into the mixer, there is no noise at all. The ground switch doesnt make a difference. Phantom Power on the mixer is OFF. I want to be clear, There is only one cable plugged into the Helix connecting from the Right XLR out to a MIC channel on the mixer. There is no signal. Just alot of HISS. Any ideas? Thanks!

Hey! So I've been dealing with this issue for seriously a year or two, but it's gotten insane the past couple months where it's every single time I start up my computer. Needed to finally make a topic since it's never been described exactly like this for me. Here is a video link to see what's happening: (If there's a more preferred way to share this just let me know please) Dropbox Link for UX2 Hiss Video I will need to unplug and replug my interface in for an unknown amount of times before the issue resolves itself. Sometimes it breaks the driver and I reinstall the UX2 drivers to get rid of the blinking red lights and it works again for the time I have my computer booted up. The noises vary but are similar. Some high pitched, some with a rhythmic pulse like it could be the power source, I have a battery backup surge protector everything runs through. Others sound like a High-Pass is on it, and some are bassy. Never know what you're going to turn the monitors on for and hear. I've tried switching the ports I've plugged into, taking every other plug of my UX2 out and replugged them in with varying orders, turning knobs while having it plugged in and out, etc. I have Mackey MR5s if that gives any help somehow. And I have attached an HTML and TXT file for my CPU info from CPU-Z KYLE-NZXT-DESKT.html KYLE-NZXT-DESKT.txt

Hi Guys. Ive had a UX1 since pod farm 1.0 maybe 13 years ago at a guess. I recently tried to start using plugins in reaper with IRs and also standalone Amp sims like Cali Suite by Neural DSP using my UX1 as the interface. But I've run into some crazy electrical noise I've never had before on both of these am sims with IRs loaders builtnit. I normal using podfarm for scratch tracks. I've tried the usual changing cables etc. But I cant figure out where its coming from so I am wondering if is possibly the UX1 itself. Also Is it possible for these super old interfaces to run IR based sounds? Just wondering as if not its about time I bought an upgrade. Asside from my PC components (PC is a pc specialist build) im not sure what else it could be so I am hoping y'all have some ideas? I can supply samples if needed. Much appreciated!

HELLO LINE 6 BUDDIES! I'm two-track recording an acoustic guitar with my POD HD500X as the audio interface. I have a RODE NT1A condenser mic plugged into a mixer with phantom power. This mixer is then connected to the POD's 'Guitar In' input via guitar lead, and there is also an acoustic guitar connected to the 'AUX' input for a direct signal. This is all running through Logic Pro X on my Macbook Pro (Early 2015) with 16GB RAM. I have used this setup before and it has all worked fine, except today I am hearing intermittent static coming from both inputs at seemingly random intervals. It sounds like a short burst of a bitcrusher-like sound, and then goes back to normal after less than a second. It can't be any problem with the mic/mixer because I am getting the problem on AUX (direct input) as well as the Guitar In (mic) input. I have tried different USB cables, and have tried different power outlets. I have also tried a different audio interface (that can unfortunately only handle one input) that didn't seem to have the same problem, leading me to think that it also isn't an issue with Logic Pro X... SO... Has this happened to anyone before, and can anyone think of any reason this might be happening? Yeah, I've turned it off and on again ;)

I'm trying to record into my DAW using the USB cable however I'm experiencing pops and clicks in my studio monitors and my headphones with audio playback or live guitar playing.. I've also noticed that the signal seems to double slightly when connected via usb. I've located the issue to the USB port causing the issue. I done this by changing the USB cable with another one to see if there was any noise and there still was. can someone please help as I will have to call technical support otherwise and mybe have to send back my new line6 helix :( and i don't want to do that because all the other audio connections work fine

Hi there, first of all, happy new year to everyone. I'm having big issues with my Helix using it together with my tube amps. I got my Helix a few weeks ago, the plan was for it to replace my big a** FX rack. I wanted to use the Helix for FX only (in four cable method) while getting my base tone from my 3-Channel Tube Amp(s). That plan failed for now, because in the current state it's unusable. When connecting the Helix to my Amps, a giant noise floor gets added. It can be barely heard using the first (clean) channel of my amps, but when using the 3rd (high gain) channel of the amps, the noise is so loud it makes the setup almost unplayable. I have made a few tests in my home just now, with the following basic setup: A fresh, empty preset in Helix, all outputs set to instrument level, and a volume pedal block added before the output of path 1A. No volume control in the Helix, be it in the input of the path, volume pedal block, the output of the path, or the big knob has any influence of the level of the noise. Both stage amps I own show the same behaviour, so it is very unlikely to be a fault in one of the amps. Both amps are custom hand wired amps that I designed and built myself (before you ask, yes, I am qualified for that, and the amps are built to a very high standard, not some kind of botch jobs :) ), so no use asking for the amps' brand. Both amps have been on the road with me, playing reliably for the past years and working flawlessly with my, in terms of noise grounding etc. far more complex, rack system. Or so I thought... Anyway. I am beginning to suspect that my Helix unit is faulty. Before I go through the hassle of returning the unit I wanted to ask if anyone here maybe has had similar experiences running the Helix together with a high gain tube (pre-)amp. I have attached a sample of the noise. I quickly recorded it with my mobile, as I don't have a recording setup at home. In the sample you can hear the change in noise level when I plug the Helix into the amp's input jack. I held the mobile right in front of the speaker cabinet. First you hear some buzzing from the amp with nothing connected, then the click when I plug the guitar cable into the helix, and then I plug the other end of the cable into the amp's frontend. The amp was switched to its high gain channel, master volume set a little lower than stage volume. No guitar was connected to the input of Helix. As you can hear, the increase in noise is really huge. Any help or suggestions are highly appreciated, I'm really frustrated. Thanks, Nils Edit: deleted sound sample to avoid further confusion.
