I had a USA one for a short time, thought it sounded good, had a Haynes mod.
Sounded Marshallish but that might have had something to do with the el34 powrramp I was using.
There are made in USA and Japan versions. I think the USA are supposed to be more desirable.
They're cool. Typical Soldano type tones. The power amp you run it thru will play a big part in the end result you get. They're a bit noisey. I prefer the Japan version myself.
