14" x 38" x 4"
The body of this is made from a fuse box. The neck is a piece of aluminum that has wires for the first 5 frets, and the rest of it is fretless. The silver box at the bottom is a small amp that you can plug into if needed, or use a regular amp. This is an 'alto bass', because it is missing the low E string. There's a video of me playing it here.
