won this on ebay for a pretty cheap price.
unfortunately it arrived and footswitches were $%&#ed. however, since i wanted the pedal and also won it so cheaply i just bit the bullet and replaced the flimsy PCB based footswitches for proper ones.
works great now and sounds good. this will be *extremely* convenient. can't wait to use it live!
you can program three different sounds into the different switches - i've got a sort of clean/crunch/lead setup.
now own a few SansAmps:
GT2
Character series British
PSA 1.1 (soon to be for sale)
original rack unit
generally I go straight into the house sound system with them, with just a dash of reverb. i love them because theres no digital fizz or latency and they've been so far 100% reliable (touch wood). the disadvantage is they are missing a bit of value reactivity and don't clean up as well as they might when rolling the guitar volume down. this tri-ac seems better than my other units in this regard, it sounds slightly different. and anyway, the three sounds i can switch between will do everything needed.
