The Proline PSS10 universal metal sustain pedal features switchable polarity that allows compatibility with nearly all keyboards with a 1/4" sustain jack—Yamaha, Roland, KORG, Williams and much more. Its rugged metal chassis and heavy-duty rubber bottom tread keeps it from moving while play, while the internal mechanism offers silent operation on stage and in the studio. It includes a top-quality six-foot cable with 1/4" plug. Proline keyboard pedals are designed and built for real-world working musicians who want to expand their expressive control. Each is designed for long-term reliability, playing stability and durability for many years to come.
