The only way to do this is to have each amp provided with its own input, not chained together. The note would need to be delayed before being sent to the next input in the circle.Hmm. Idk how to phrase this, so bare with me;
Would it be possible to chain/link like, 10 combo amps, place them in a circle, and use some kind of sweeping effect to get a note to travel smoothly around from amp to amp? Like building a "3d" or surround system with combos and direct input
I'm guessing it would require making a custom unit with X amount of outputs, but could technically be based on existing rotary pedals..
Could be fun to just try without that effect too. Like, have a circle of amps.. You'd face them inwards for when you practice, and outwards for gigs, and stand in the middle like in a bassnado™.
Rotary effects often vary panning between left and right channels, which isn't the same.
