That is fair enough, thank you for all your help. I've been suspecting the extremely cheap attenuator has been a problem for quite a while and was hoping coming onto this forum would reveal I'm doing something wrong with the HXS that wouldn't cost money. You're right, for what I want to do with the HXS and amp (DI and reamp) it isn't worth all this hassle right now, I'll cross that bridge again when it comes to it. I'm extremely happy with the convenience and sound quality of the HXS as-is, the modelling far surpassed what I expected after my experience of other modellers and plugins. Thank you again for your time, I really appreciate it!

Early update, seems that the attenuator is the issue but it is strange. On step 3 (guitar > stomp > amp > attenuator > cab) the feedback started, before that was fine. I noticed, when everything was in a loop before, that the light to indicate the noise gate being active on the Precision Drive was always knocked off - it exhibits the same behaviour here, even though there isn't a loop. So it seems the attenuator has a real problem with the HX stomp being in the signal chain and it affects everything because of it. Is it still worth continuing down the path with the new cables? Does it look like a new attenuator is the key? If so, is there an affordable one recommended? Edit: OK so interestingly, when the attenuator is in the signal chain, HX Stomp BEFORE amp causes a problem but HX Stomp AFTER amp is fine: Guitar > HX Stomp > amp > attenuator > cab gives feedback Guitar > amp > attenuator > HX Stomp > Headphones/FRFR works fine

Excellent, that's all ordered along with a couple more instrument cables as I've literally never had to have this many before. I'll crack the multimeter out ready, just in case there's no documentation, as I can't see a random cable company following any standardisation as to whether TIP/RING is SEND/RETURN. I'll update you once either complete step 5 or encounter the issue. At this point I'm expecting whatever the problem is, it's going to be an expensive process to rectify it.

Hi, I think we're in different time zones so apologies for the long delays on my replies. I'll need to buy the TRS to dual mono cable is this what you mean?: https://www.amazon.co.uk/6-35mm-Splitter-Insert-Vitalco-Adapter-Black/dp/B07WTP3TLV/ I think I understand the steps correctly but just to confirm: Normal playing amp into cab As above but with attenuator between amp and cab Like 2 but with HXS from Mono/L OUT (rather than FX Send) between guitar and amp input Similar to above but HXS and amp in 4CM with the FX Send L half of the INSERT cable above above going to amp input Same as 4 but connect attenuator Line Out to FX Return R. Then the TRS dual mono should be splitting the L and R FX Sends (I think that is what you've done with panning) to take the right half of that to something which will accept sound? Only thing I have that takes 1/4 input like that is my other interface so I'll do that. If I've gotten that right, that's really straight forward and you explained it perfectly. I'll take a day or two (depending on deliveries) to get this done but as soon as possible, if you could confirm that I'm looking at getting the right cable. Thanks again so, so much!

This happens on the lead channel regardless, with the tiniest bit of gain, and I want to play with gain anyway. Also standing further away does nothing sadly, this also happens whether there is a guitar plugged in or not. I have recorded two files: cleanworking.mp3 This is a relatively quiet simple chord that works absolutely fine. leadchannelfeedback.mp3 This is uncomfortable to listen to do turn your headphones down a bit! I play a similar chord but then switch to the lead channel and as the chord dies the feedback begins. I then mute the strings and quickly show that switching back to clean works fine. None of this behaviour happens if I play just through my amp to a cabinet, through my amp into attenuator into another interface, or into my amp and then into the HX stomp after. It only happens if amp receives from the HX stomp and then returns back into it. Thank you so much for persisting with this, I'm completely lost here and have no idea how to address this issue. cleanworking.mp3 leadchannelfeedback.mp3

Update - the DI box with ground lift made no difference. However, I did narrow down the issue with something I should have absolutely checked before - the clean channel works perfectly, it is only the lead channel, when gain is involved, that there is any feedback. If anyone has any thoughts, suggestions, etc. please do let me know.

Thanks for the reply, rd2rk. I have tried without the OD and I still get the feedback, it is a different pitch but feedback all the same. Everything is running from the same power strip, I'm not 100% sure if it is filtered but it hasn't caused a problem in the past, is it that likely that adding an extra device would cause it to go from 0 to 100 on the feedback? I will try one of these, like you suggest and see what happens. I deliberately got the HX Stomp to be an all-in-one for DI and reamping so I hope this works, the modelling isn't particularly important to me.

Hi rd2rk, thanks for this, I didn't mean to make you guess. I was trying to be thorough, just not to the extent you wanted, it seems. Apologies if any (most) of this still is extremely amateur, I'm new to a lot of this more in-depth gear routing. I've attached a diagram of the physical setup to assist in describing it. All cables are, to the best of my knowledge, TS instrument cables apart from amp to attenuator which is a speaker cable. The intention is to use headphones from the headphones socket, and USB into a DAW (eventually) so I can DI, record, and reamp using the HX Stomp. The routing is as follows: Guitar > L Mono input of HX Stomp with TS cable FX Send of HX Stomp > pedal with TS cable Pedal > input of MT 15 with TS cable 8Ohm speaker output of MT 15 > 8Ohm speaker input of Harley Benton PA-100 with speaker cable Line out of Harley Benton PA-100 > L FX Return of HX Stomp with TS cable Output through headphones of HX Stomp I'm yet to try USB into DAW, I've tried this setup with and without USB connected as I saw you post about that feedback in another thread, it didn't make a difference. Prior to attempting this with the HX Stomp I was using the same setup apart from guitar went direct into pedal and attenuator went into a Native Instruments Komplete Audio 1, this worked fine with no feedback. I've also attached the patch as you requested, it's extremely simple. The intention would be to have an IR after the FX loop, and maybe a compressor prior to it. Thank you for this, it was getting late when I posted and I had tried isolating them and setting the input as line but I don't think I'd done it correctly yet as I was rushing. I think I might need a DI box or a reactive load with a ground lift or something. Very sad times, I was hoping the HX Stomp would save me money from having to buy DI and Reamp boxes. MT 15.hlx

Hi, I'm having a similar issue with different equipment; so rather than make a new thread I was hoping I could jump in here and confirm what I need to do. I'm using an HX Stomp, OD pedal, PRS MT 15, and a Harley Benton PA-100 Power Attenuator. The aim is to use the OD pedal and MT 15 as replacements for OD and amp blocks in the HX Stomp as follows: Guitar > HX Stomp (effects send) > OD Pedal > MT 15 > Power Attenuator > HX Stomp (effects return L) The HX Stomp is set up with a really simple patch that I figure may be incorrect: Main L/R in > FX Loop (I'm assuming this should just go through OD pedal and amp) > IR > Main LR out I'm getting similar feedback as described, to the point the amp's electronics are audibly squealing concerningly loudly. I'm not plugged into a DAW for the USB 1/2 and Output 1/2 feedback as described in another recent thread. Would I need to either buy a DI box or alternative loadbox to isolate the ground? Am I doing something incorrect with the patch? Thanks in advance!
