Here’s another solid-state amp that’s had its unloved innards removed and an SE-5a circuit added. Joel’s donor was a Rickenbacker TR7. As the second photo shows there’s plenty of room, and it only took some drilling to add the holes for mounting the individual components.
“I tried it with several guitars (Rickenbacker, Charvel, Fender, Hofner), 6 & 12 strings, single or double pickups… it’s great in every case (after a few minutes to find out the right control setup). The best surprise occurred when I plugged my Yamaha Silent nylon guitar and got a pleasant ‘acoustic classical sound’ through the Jensen speaker.”
