Hi POD users, I've got this problem: I always played with one guitar through pod and my amplifier using 4CM because I use my amplifier's pre. Now I want tu use the second input as a separate source, so I moved my FX loop block in the upper Channel A, while in the Channel B, i'm using the signal of my amp slaved. The problem is that when I moved the FX loop, I noticed a consistent increase of gain (maybe that famous 6 db of send signal that were missing using 4CM) Have you tried using 4CM only in one Channel, instead of both?? Is this a Known issue??
