I have a 50 lb. tube amp that I use for gigs and it is completely satisfying. But I want an amp that I can take to jam sessions and rehearsals that is small, small enough to carry with one hand so I can carry my guitar in the other. I have been using an Acoustic G20, and I actually like it a lot. It is a solid state amp that you can buy for peanuts, but it has a surprisingly tube-like response, both on the clean channel and the overdrive channel. It doesn't have the clarity and definition of a tube amp, but it has a bit of that "sag." But I recently upgraded to a fully hollow guitar, and suddenly the G20 doesn't seem to have enough headroom to handle the tone produced by the hollow axe. Also, at some of the louder jam sessions, the 20 solid state watts weren't quite enough to be heard. Acoustic makes a G35, and that is an option I am considering, but I wanted to activate the wisdom of crowds by posting here. I am interested in some of the minuscule but powerful amps that are out there. I can't afford the DV Mark Little Jazz or the Quilter Micropro, and from what I have seen on YouTube, they both sound rather sterile and dry. I can afford the ZT Lunchbox Junior, but I have seen some comments indicating that it can sound nasty. I had a Polytone Minibrute back in the day, and that was a good amp. I could look for an old one, since apparently they aren't made any more. The Roland Cube seems to have a similar tone, and that is definitely an option. But it would be cool to get an even smaller amp if it sounds decent.
