Tech 21 Trademark 10

has anyone here ever played through one of these? i got one for a steal from a guy i connected with through here... it's an awesome amp... totally gigworthy (through a PA, that is), my only concern with it is the single-channel... i'd like to set up a clean fender tone on one channel and a dirty marshall tone on the other, but alas, one channel. but otherwise, it's a GREAT, GREAT amp, the best small amp ive ever used, possibly the best amplification idea in years... all analog modeling, responds alot like tubes, doesnt feel lifeless or dull... i dig it. Any other opinions?
