P00PDOG Posted March 23, 2014 Share Posted March 23, 2014 Hey all, I have been perusing these forums and have learned a lot but haven't seen any posts on exactly how/if this will work... Right now I have a pedal board with a wah, compressor, tuner, and a "buffered" AB box. I have a Marshall 6100 LM half stack and a Carvin MTS3200 that powers a matrix NL212 cab. When I plug the AB box into the instrument input on both amps I get this crazy oscillation that sounds kind of like a slow record scratch....its really loud and makes my two amp experiment un-usable...I got through my band practice by using effects send from one amp to the other amp's effects return, but it still sounded off to me..one amp was fine but the one slaved sounded bad. What I am trying to accomplish Use a POD HD 500X/ProX for compressor, wah, maybe distortion pedal, and tuner....then straight to the instrument input to each amp so that I get the full sound of each amp, but no horrible record scratch oscillation.... I had my amp guy explain to me that this oscillation would stop with a buffered AB pedal but the road rage pedal that I got didn't work :-( Is there anyone here doing something similar here using a POD (any version)? Also I apologize in advance if this has been discussed already and I somehow missed it... Quote Link to comment Share on other sites More sharing options...
jandrio Posted March 24, 2014 Share Posted March 24, 2014 It seems that u r in2 a "ground loop" symptom.Does ur "buffered" AB box have a ground lift switch?c attached img.Check out this one. Alternatively, u cld just feed the L output of ur POD to one amp and the R to the other. In any case, u shld take in2 consideration the ground loop.

P00PDOG Posted March 25, 2014 Author Share Posted March 25, 2014 First off thank you for replying, I was beginning to lose hope...My Road Rage does have a ground loop switch and I used it. it reduced a bit of noise but that strange noise was intermittently still there....Also, I don't have a POD yet, I was trying to make sure that this wouldn't happen with the POD before purchasing it, but I can't be the only one trying to have 2 separate amps, so I am guessing that this will not be a problem with the POD...so I am going to take the chance on it. Oh and that Big Shot would probably have done the trick too thanks again...

cbrfreak Posted March 25, 2014 Share Posted March 25, 2014 I can confirm for you that my POD HD500x is running two seperate amps with no issues at all. One on the right channel and one on the left. Quote Link to comment Share on other sites More sharing options...

What you want is perfectly doable with the 500X or the Pro. Set up your FX chain inside the POD however you want using no amp modeling and you will be able to pass that signal out the left and right outputs, one to each of your amps. You can also place any of your current pedals in the POD's FX loop. If you want to send the exact same signal to each amp, set the mixer as the last block in the chain and pan both sides to center. If you want to send a completely different set of effects to each pan hard left and right and that way each signal would be completely separate. For instance a clean signal with delay and compression to one amp and a heavy signal with distortion or overdrive to the other. This will open up a whole new level of possibilities for you... 1 Quote Link to comment Share on other sites More sharing options...

Thanks for the clarification guys, I feel much more confidant getting a POD HD now... Quote Link to comment Share on other sites More sharing options...
