3-string uke banjitar. It really plays (if you set the bridge right) though not very loudly. Designed to easily add a piezo pickup and a 1/4 inch jack.
Remove pads from neck. The neck is epoxied and snaps into the body... try to give it a little relief if you can i.e. angle it away from the front of the instrument. The head is epoxied onto the other end of the neck. Extended bridge is superglued to the front plate to set the intonation. The front plate with attached bridge then snaps into the body and is held in place by string tension.
There's a hole for a 1/4" jack in the side, and you can glue a piezo element to the backside of the front plate (under the bridge) for amplified or processed banjitar madness.
You can try different strings, I used the D, G, and B steel strings from a set of electric guitar 10's I had lying around, but you may want to try nylon or other types of strings.
