"Circuit from a Korg Monotron Delay, put into a custom-built case with a larger ribbon and force-sensitive volume control. 3 x 17 x 1. The faceplate and backplate are both 1/8" tinted acrylic around a 3/4" MDF body. Runs efficiently on two AAA batteries (not included) replaceable by friction-fitting them from beneath. Intended for tabletop use, with clear rubber feet on the underside.

There are no mechanical means of attachment between the plexiglass front and back plates and the wooden body; they're permanently glued on with silicone. So hacking into the circuit isn't much of an option, unless you want to re-glue it all together. And the sides of the piece are black electrical tape. There are a few cosmetic flaws, in other words, but it's a handmade, one-of-a-kind prototype instrument, and it plays magnificently.

From left to right: volume knob, slide switch, volume pad (the switch disables the knob and enables the pad, and vice-versa), traditional layout of Korg Monotron Delay controls (power/waveform select slide switch, two LFO knobs, VCF knob, two delay knobs) and a switch that isn't wired to anything; Its intent was to reverse the direction of the ribbon, but I couldn't get that going, so now it just sits there."
