I used to play a Marshall DSL 100 and that thing sounded like crap. The footswitch is easy, with 2 channels and 1 combined. My guitar is a musicman silhouette. I can't get a real heavy solo sound out of it. The clean channel is ok.
Clean channel is very sweet.
Just purchased a triAxis though, and the things killer. I haven't gotten bad sounds out of it yet. Drives headphones, is O.K. direct to tape, good out to mixer, haven't tried out to pwr amp. With the Les Paul, I got great Allman lead sounds out of the blues channel, and Slash-type gain on Solo. Like I said before, it loses attack as you raise the gain.
