This is a pro piano-style damper (Sustain) pedal offers realistic half-damping effects when used with Korg products that support half-damper control. It can be used in place of any momentary or sustain pedal - the half damping control will not interfere with normal operation on other types of products. Korg momentary pedals use "Normally Open" or "Negative Polarity" circuitry.
This pedal is used and shows light signs of love but works great. Ships the next day.
