I just got one of these yesterday. I had been seeing them on the GC used gear website for $79 but haven't found a lot of info on them around the web. The little bit I've found has been good but just not many sources for how they sound, how well built they are, etc.
Anyway, the GC in Detroit had one listed for $49 so I called them up and got the story. Most of these aren't used as in pre-owned but were demos, floor models, etc. The one they had in Detroit looked and worked fine according to the guy I talked to so I ordered it and got it in. He was right. It looks brand new. I can't find a scuff or any sign of wear on it at all and, although I haven't played it much yet, I'm pretty impressed with the sound.
It's got some kind of Chinese tube (12ax7) in the preamp and a SS power section but it has a pretty smooth overdrive sound with the Vol turned up and the Master turned down to bedroom levels.
Definitely worth $49.
