Other than it's weight, can't complain about this all! Am not techy and it has 3 knobs; Volume,Treble, and Reverb that do what they say. At home at low levels it's clean and I can use pedals - at rehearsals / gigs I can turn volume up and don't need to use pedals at all - it has lovely natural drive of it's own. Usefully there is also two input jacks; normal and bright - I A/B into them to switch between them depending on wether I'm using guitars with single coils or humbuckers. Never had a gig yet where someone hasn't stopped to comment on how cool it looks either!
It's a little predictable that the only solid state component on the amp is the part I dislike. The Vaporizer uses a pair of op-amps to drive a real reverb tank. That's the good part. The bad is that those op-amps don't seem to have the gain for the job, leading to a very quiet reverb channel. Still, the amp is good enough that I use two in stereo. Get one for the amp sound and the style, get a real reverb tank for the surf wash.
