I'm putting together a looping setup. I have a few instruments that I will use: Guitar, bass, piccolo bass, and electronic percussion (handsonic, wavedrum or similar). I want the guitars and basses to go through a pedal board. I currently have a M13 and will likely add some others (ravish, pog2, and ?). Everything will need to go through the looping pedal. I am waiting to get a Boomerang III I bought here in the classifieds. My thinking: Run everything through an inexpensive mixer (Mackie, Peavey, Yamaha or similar). Have the pedal board in the mixer effects send/return. That way I can assign the instruments I want to go through the effects and have some basic EQ for each instrument. The output of the mixer will go through the Boomerang and the Boomerang out will go to either a powered PA speaker or my GK MB500 Fusion into a full range speaker. Am I way off base? I have always been a bass>>>amp guy. Decided it is time to expand my horizons. If this is all wrong, any advice would be appreciated.
