Hi, i just recieved a Coliseum Lead that i had purchased, and seeing as it has both a reverb unit and vibrato, i figured that it would probably be footswitch compatible, but after inspecting the back of the amp it doesnt seem as though there is an input for a footswitch. I'm curious if anyone knows if this unit is footswitch compatible and if so, could i purchase just any two button footswitch or would i specifically have to purchase a sunn footswitch? Thanks alot.
