Hi I have a JVm410H and I'm looking at buying a Gig Rig G3 programmable footswitch so I can store various pedal combos, and then switch with one push, both the pedal combo I want and also the Marshall channel I want at the same time.

Is this possible using a) the Marshall footswitch or b) using the MIDI In/Out on the head?

Any help most appreciated

Cheers
