I don't care if they are solid state or tube I would buy one. I did notice that they were tube amps though. I did actually see some little bitty combo ones in a local store. They probably had and eight inch speaker in there. So I think that they were probably solid state. If they had a full size amp in stock I would have gotten one.
I have seen these amps in videos quite a bit for the short time that they were on the market. Since they were only on the market for a short time something other than sales must have happened.
