I'm also using the HD500X in 4CM. Some of the old posts about levels being too low etc on the HD500 don't apply to the HD500X I'm surprised with your immediate feedback, I recommend some level verification first. Put the HD Line/stomp to line. Start with an empty HD patch. You want the level going from the HD Efx Send to the Amp to be the same level as your guitar. You can do this by ear by just swapping cables back and forth between your 4CM setup and plugging the guitar directly into the amp's guitar in.. If the HD Efx Send is not unity, play with the HD Input setup - I had to set the HD second channel input to either Guitar or Variax to get unity gain - sorry I don't have the exact answer, I'm not at home and won't be able to get back to this until tomorrow. Again, your goal is to have a signal at your amp input to be guitar level, so then you can add gain/od if you want. Generally, wah, od, distortion, compression go before/into the amp's preamp. Time based effects like delay/chorus/reverb belong after the amp's preamp or in the amp's effects loop. Again, generally. EQ, noise gate, can go either and I use in both. Keep in mind in 4CM you have 3 ground paths between your amp and the HD (4 if you're running midi). This can cause ground loops, which can result in hum, hiss, or even a weird filtering sound. The 3 cables going back and forth between the HD and the amp should be bundled in a snake. If you have any of these problems, lift the ground on one end of two of the three cables (but not all three cables.) Ideally you one want one ground between the HD and your amp. If running midi also, break off pin 2 (shield) on the cable on the amp end - midi spec states the midi receiver (the amp) shall not ground pin 2 - but the JVM does. Does you amp effects loop have a -4/+10 switch? My JVM does and that's the big question I have. Running at -4 on the JVM attenuates then boosts the signal (which can cause extra noise/hum) while +10 is straight thru. I wonder if the HD has enough headroom in its digital signal path to handle the +10? Again, does the HD has enough headroom in its digital signal path to handle the +10 in it's effects loop? Later.

I just found on YT a pedal by Fender called the Runaway Feedback pedal - in listening to the demo, it sounds like what you described - I'll try to give this a shot soon.

Players, I'm looking for that magic moment of melodic feedback, which I always struggle finding. And I'm not talking about the squeal of unpotted pickups, I want a note related to the one I'm playing. For gigging I use the H&K GM36 and the HD500X as midi controller and input effects like wah, OD, EQ, etc - no amp modeling. I play in a 7 piece so cranking my amp to 10 is not an answer for me - although I can play loud(ly). I am using an SG with moderate gain SD pickups, and sometimes use an LP Special with stock P-90s. On a side note, at band practice I use an old Digitech GNX3000 into a solid state power amp, and I can get that to feedback rather easily. And that's at a fairly low volume. Is it a natural compression in either the Digitech or the power amp? Do I need a compressor in the chain? I mostly use mild to moderate saturation, although I occasionally set the amp to mimic the Soldano buttery saturation. So just cranking the gain isn't necessarily an answer. Have any of you found some amps feedback better than others? Help me Mr. Wizard?

I use my HD500X as a MIDI controller for a H&K GM36 - and for input effects like TS, wah, volume pedal, EQ (mid-boost per meambobo), compressor, etc. And if my H&K dies at a gig (I have an inherent distrust in tube amps), I can use the HD as a backup straight into the PA. So I have an amp, a 1x12 cab, and one box on the floor. And I can get many really good tones. And have redundancy fail-over. That's why... -Bob

Sort of related, Jennifer Batten used to proudly show off her GNX-3000. Wrong brand, but she had no problem showing she was modeling. Vai uses a Carvin Legacy, but always stays on the clean channel. He displays than amp proudly, but models most of his tones. Of course, he's using the expensive (and probably free) modeler. One can only hope if you are lucky enough to be sponsored, it's something you'd actually use...

This is what I use http://www.goclc.com/products/Work-Gear-Softside-Tool-Carriers-Bags-Backpacks/1111 Put my 4CM with power and midi snake, extra hoses, and HD500X on top. It has held up well, and very much protects my HD500X GC tried to sell me a case that looks like the stitching would fall out immediately, and wouldn't protected my HD from a fart.

This has been submitted many times on Line6 IdeaScale - hopefully someday they notice... Very first gig with the HD, I stepped on it during sound check - no idea what was happening and had to reboot the HD. Now I know just to hit it again, but I NEVER USE IT!!!

It's a feel - particularly dynamic response. Hit the strings plugged into a Marshall, and hit the strings plugged into a HD500X driving a power amp with even more power than the Marshall, and tubes still have this tactile feel. No model on the HD500X I found can rival the response to pick and guitar volume dynamic like a good tube amp. So I just bought a H&K Grandmeister 36 ($1100, 18lbs), and use the HD for input side effects (noise gate, compressor, tube screamer, wah, volume pedal) and for midi control of the H&K. For me, that combo feels better than the HD alone. Someone mentioned price - fortunately for me, my amateur band makes enough to pay for my gear - nice hobby. Now once it gets put thru the PA, maybe all is lost. But on stage, it feels better. To me.

I modeled for years with a singer/songwriter, so I was the only electric guitar in the band. My "amp" was a gutted Vox 1x12 cab with a Crate Powerblock for my modeler's poweramp. People would come up to me (especially guitar players) and tell me what great tone my Vox had :D Then the guitar players would notice my modeler, and turn their nose up and walk away - while I laughed AT them of course. Now I am in a Allman Bros tribute band, two guitar players. The other guitarist is using tubes. Side by side, you can tell a modeler from a tube amp. In this band, no one every told me I had good tone until I got a tube amp. My $.02 -Bob

I think the HD is as fine pedal board into the front of my tube amp - I just don't model any amps. Using the HD500X to control the H&K Grandmeister (GM) 36. I am a midi noob and this just works. I can get a ton of tones. I run the HD into the guitar input of the GM (not 4CM) and a midi cable. The GM's reverb, delay, and simple effects are plenty good enough for a classic rock performance setting. The HD runs wah, volume pedal, compression, EQ, noise gate, gain (patch cable across effects loop), and distortion - and midi controls the GM. It's like modeling with tubes - I don't think I've ever been happier with a system.

I have a cab at practice and almost the same cab in my bedroom. In my bedroom I use this, and it helps be get close to practice/gig sound because I don't' have to change my HD or amp. http://www.parts-express.com/speaker-l-pad-attenuator-100w-mono-1-shaft-8-ohm--260-265 My $.02

Crate power block. Every time I see one on CL or eBay I'm tempted to buy it just because. I'm currently using mine as part of an active power soak, but I used it with a modeler for years. If my main tube amp I'm using for gigs doesn't work,I have patches in my HD to model straight into the crate.

OP, did you fix your problem? I did a gig last weekend with your exact setup, worked so well I'm trading the TM36 for a GM36. Btw, both amps have digital solid state control components, it sounds like you zapped it with ESD. Maybe it recovered after a power cycle... Also, the GM36 has good enough effects I'm not using 4cm any more...

So yes, an educated guess would be Line would be higher level than Stomp - does it then also adjust the Return sensitivity/gain? A stomp box (and the input section of my amp) could or probably have lots of gain.... I realize I can "play" with this, but when I buy a tool I'd like to "know" what it is doing and how to use it...
