William Brethaur's Onyx
William built this Onyx pedal based on the Matsumin Valvecaster design with footswitchable tube and solid-state distortion added in. The knob on the far left blends the distortion with the dry signal. The tubes are guarded by old pickup rings, while the input/output and power jack plate is made from a Laserdisc of "Stripes."
