I have an HX stomp running 4CM into an Engl Fireball 25, which is running into a Revv 112 cabinet. With a normal pedal chain (ODs in front, delay in the loop) everything is fine - and the amp is a fire breather.
If I use the Stomp in 4CM with a preamp swap I'm getting a huge volume drop. The volume knob and the channel volume are at maximum. In global settings I have input level at Inst, output level at Line, Send/return (r&L) at Inst (doesn't seem to do anything to switch to Line), and return type set to Return.
I'm hoping there is just something dumb I'm missing. I really really want this to work.
