Hello Currently I'm the only guitar player in the band and I often have to switch between lead and rhythm. Right now I'm doing it with a cheap effects processor put into clean channel of the amp. I have effects (distortion, delay, etc) for both roles and use a footswitch on the processor. But our new rehearsal place has high-end tube amps, and using cheap digital effects with them would be a waste. So I'm interested in what equipment do I need to set and switch presets, while using distorted channel of the amp. Thanks in advance.
