The Convenient Expression Tool for Today's Electronic Keyboard A product for keyboard players who want the most realistic pedal action. It is used in the same manner as the sustain pedal on an acoustic piano. This classic-style pedal works with any most brands of analog or electronic keyboards including CASIO, YAMAHA, KORG and ROLAND keyboards and synthesizers. Designed to work and feel just like an acoustic piano's sustain pedal, it has a specially designed rubber bottom that grips the floor and stays put while you play. This is a high-quality damper pedal with expressive half-pedal capabilities.
