Fun pedal in good condition. Includes power supply. Just turned out to not really be my thing.

The Electro-Harmonix Bass Mono Synth converts your electric bass guitar into a fat-sounding monosynth without instrument modifications, special pickups, or MIDI. There are 11 synth types to choose from, and there’s plenty of room for extra tweakability. And after you dial in a sound you like, you can save it as one of 11 user presets. Beyond that, you get an expression pedal input for real-time parameter manipulation.
