the Amp1 is just an amp.
What I have now is a boss ms3 in stereo.
So left out of the ms3 goes back in to the poweramp of the amp1. the speaker out from the amp goes to a left side IR box, which has a thru for the guitarspeaker.
The right side of the boss goes to an IR box, with a thru which goes to a powered guitar cab.
I basically want to get rid of the IR boxes with the HXFX
