My apologies in advance if this is redundant. I too have a Boogie Mark V and am very interested in knowing if I can control it with a Helix floorboard (as opposed to the rack mount unit).
The amp has three channels, a solo boost and an eq boost. It has 1/4" external switch outs on the back for channel 2, 3, solo boost and eq boost. I'm assuming channel 1 is on by default when channel 2 and 3 aren't switched on.
Can I used helix's EXP2, EXT 3, EXT AMP and/or CV to switch all of these on and off?
Can I use a TRS cable with EXT AMP to switch 2 of the channels if CV isn't an option?
