Hey all - I recently picked up a JTV-59 and love it. I run it into my POD HD500 and Marshall JCM900 using the 4 cable method.
For any of the modeled presets it sounds great. I run these into the effects return on the Marshall..
Before the JTV, I ran some presets through the "front" of the amp using the FX loop block in the HD500 and the 4 cable method.
Now with the JTV running into the HD500 through the variax input/VDI, I get serious feedback when I try to engage the dirty channel.
Basically the FX loop doesn't work.
I tried to a/b the output from the HD500 (one to effects return on amp, one to front of amp) and only the effects return works.
Anybody have this problem? I want to run the JTV through VDI to control models and supply power. But want to option to bypass HD500 amp models and go into front of Marshall for the dirty channel tone.
Advice much appreciated.
