Digitech GSP 1101. I don't feel it colors the tone, I put the RM4 in the GSPs effects loop, so Boost/ODs, Compressor & Chorus/Phaser can be placed out front of the preamp (Compressor & Chorus can also be placed after the preamp. I am also a fan of one button changes, not having a bunch of long cable runs, & versatility, which is why even though alot of pedals sound awesome, I am not a fan of pedal boards. I have created some patches that using the Control button will switch effects in/out & boost the signal so I can go from a rhythm tone to a lead tone without having to program a seperate patch.
One problem I am having with it is trying to use the expression pedal like a volume pedal to clean up the signal for cleaner parts. But that just may be, midiot me/operator error, & not the unit. If anyone has had some luck programing that in let me know.
