I just built one of those cigar-box guitar amp kits…
I got the amp in kit form from GuitarFuel, for under forty bucks. It arrived in a couple days, was a very easy build, and I’m still on my first battery.
I’d found a cheap cheap deal on a Danelectro “Fab Echo” - which is their sort of retro-rockabilly slapback & reverb box - so I hacked the guts of it into the amp’s circuit. The results are pretty cool. It’s a toy, but it’s also NOT a toy - it’s a very useful recording tool for certain sounds that you’d be hard-pressed to duplicate otherwise. More on recording with it at this link.
It sounds better with a little gain, but I have a little overdrive box (hand made by guitar tech Tim Jauernig, who’s done some work on my gear over the years) which gives it a little bite. I also did the vocals, with the lovely Mrs. Cloudy supplying a harmony or two.
All the guitar tracks in this video were recorded through the little amp. For me, this video was really an experiment in getting flash animations into Final Cut Pro, and also integrating flash animation with live footage. It was fun, but man, what a tremendous amount of work.
For those into recording, there’s some more detail on getting some big sounds with this tiny amp at this link.
