Finished to the point of testing. Some slight adjustments to the bridge are needed for angle and intonation.
Metal finger picks feel the best so far when playing. I may experiment with the tone control capacitor. It has a .022uF at the moment. I have only tested with the Fender-style amp. Seems pretty mellow.
I will make several changes to the next one I build. Building these guitars is a little more complicated than I thought going in. It is not Rocket Science, but it has challenged my skill level. Fun stuff! Most likely will make a four-string next time. The cigar boxes are very fragile, and the paper covering them is especially easy to damage.
I will post some sound files when I get everything intonated.

BTW, the amp in the photo is my design and is like a Fender Delux Reverb but with twin 12 inch speakers.
