I have one of these made in 2001 by Trace Elliot. It sounds "Vox"ish with more headroom on Preamp (channel) 1 and lot more saturated dirt on Preamp 2. The low end can get a little tubby especially on Preamp 2. The Boost can be used on either channel but is the most effective on Preamp 1. I replaced all of the top hat knobs with speed knobs as they are easier to read at an angle. The key to this amp is the 5 button foot-switch which allows the simultaneous use of both Preamps. Those foot-switches can be expensive and didn't come standard with the amp. I've owned it for 4 years and it has been reliable considering how it is constructed. Everything except for the power switch and AC mains are mounted on PCB's. They all seem fairly robust but I prefer the pots and speaker connections to be hardwired for easier replacement.
Here are some pics of the amp sans the cabinet.
