The MP‑317 Phoenix Wings is a compact optical‐circuit tremolo pedal housed in aluminum‑alloy with true‑bypass switching. It features three intuitive controls: Rate (speed), Depth (intensity), and Wave, which ranges from a smooth triangle to a sharp square wave. Designed to emulate vintage tube‐amp tremolo tones while also offering modern stutter and rhythmic chop textures, it includes an LED status indicator to show operational state. Operates on 9 V DC center‑negative power.
