Can anyone tell me anything about this amp.  I've been looking around at places near me seeing what older solid state amps I can find.  While I found some on others (Gibson G-40 and Fender-M80) I've found very little on this particular amp.  Supposedly, from the little I have found out, it has true pitch shifting vibrato. I tried it in the store and though it sounded different but I just attributed it to a really big variation in volume.
