It’s not a guitar amp but it’s a something I had wanted to do for a long time and finally got around to it.
I had originally planned on building a tube based theremin, and maybe someday I still will, but for my first theremin I went with a kit. I build the 2006 Minimum Theremin from Art’s Theremin page.
The kit was very well organized and I got the whole thing going in a couple hours. I built it in an old carving knife box and i think it came out pretty well.
As far as playing it, it’s hard! Trying to play a real melody will take some practice. I did hook it up to my Guitar Pod and set it on the Orange amp model with some delay and I was knee deep in Whole Lotta Love!
I’ll get some pics and maybe a clip up soon.
