Hi, If I wanted to run 2 amps, one a switcher that will handle clean and lead with echo in the loop; the other amp will run dirty and dry and in combination with the dirty side of the switcher to blend tones (maybe run by itself as well). The switcher on clean will often run chorus and compression. The lead channel on this amp will have an tubedriver that gets kicked in on occasion. Is there a neutral sounding aby pedal that does this? Change channels in one amp and also be able to bring in another amp to run at the same time. Lavaflow, Lehle etc? If not what is the best way to achieve the goal? Thanks.
