i have a mesa roadster combo and a line 6 Spider Valve MKII 2x12 Combo and im wonder if there is a pedal that would allow me to not only play these amps at the same time but also allow me to switch channels of both amps with one stomp. i want to blend the two sounds of the dirty tone and the clean tones but i dont want to have to step on two pedals to do so. i have a morley aby switcher so maybe im just looking for a pedal that just switches the channels.
