The Cherub Keyboard Sustain Pedal is a solid pedal that allows you to sustain notes on your keyboard or digital piano. With a chrome metal pedal, plastic shell and rubberised bottom, the Cherub sustain/damper pedal will be a strong, durable and useful addition to your keyboard setup. An added feature is the switchable polarity of the pedal. You can swap the function of it so that when you are not pressing the pedal down, the note is sustained, and when you press it down it is no longer sustained.
