Just controllers mainly,
the MM4 is routed before the preamp (GT Trio and V-Twin Rackmount).
Connected with a Pedalsnake.
Handles all the bread and butter stuff
I have a second pedalboard housed on top of the rack which at the moment is mainly a PODX3Live.It's used as a DI for acoustic and otherwise only provides a synthesizer but, if needed, I can access the X3 features and use some of the crazy "pedal-sounds" it has.The second pedalboard also doubles as my direct/flyrig.
