Abstract

The Stringer is a polyphonic signal switcher for use with 13-pin DIN MIDI guitar pickups. Used as an intermediary between a guitar and a synthesizer pedal, the purpose of the device is to isolate a single string for monophony, such as bass note accompaniment. A height-and-depth-adjustable fulcrum bar supports the performer’s feet, and brings them closer to the foot switches, allowing for smoother and faster string switching. The current model can isolate strings 6, 5, and 4; mute all strings; and can run in bypass mode to pass all string signals through for standard operation. The circuit is powered by a 9V DC external adapter, and housed in a custom aluminum chassis.
