I'm pretty sure that the Boss LS-2 can run 3 different amps at once but im not sure, probably worth looking into some kind of pedal though

.
Would be really cool to have the sound of 2 different amps, i think Steve Vai does this he has a big rig for his effected tone (distorion and wah etc) amd then a little fender combo that he uses just for clean, just to give his sound more depth
