For this project, I wanted to have a headphone preamp built into the the body of the instrument. I decided to make the instrument a tenor ukulele.
The outline of the body is a aluminum rod.
The heaphone amp is powered by a 9 volt battery. The battery is housed in a little compartment on the back.
The body is basswood, the neck is maple and the fretboard is rosewood.
The output jack is is attached to a strat style jack plate.
On the top of the instrument is a combination volume control/power switch. There is also a green LED power indicator and a headphone jack.
Here’s a video demo of it:
