A two amp setup would be really easy if you had two heads. I have a Radial Headbone that allows you to run two heads into the same speaker cabinet. There are several great Z combinations I could think of. The KT/SRZ would be cool (6545, anyone?). The R66/ MazGT for a heavier tone. I think the Holy Grail would obviously be the Stingray/ Maz GT.
