I'm actually in the market for a new (to me) amp right now. I want to keep with a 15" speaker (like in my Vibrosonic), but I need something that isn't going to break on me every few months. Also, the fewer knobs the better. I like the looks of the new Supro line. Either the Thunderbolt, or the Rhythm Master would fit the bill, but I don't have anywhere to test them out. There was also a dude in the emporium selling a tweed Pro copy that sent me down a Youtube wormhole yesterday. Something along those lines would work fine, as well. 25-30 watts. I could dig that.
