Korg DS-1H Half Damper Piano Sustain Pedal
This professional piano-style damper (Sustain) pedal offers realistic half-damping effects when used with Korg products that support half-damper control. The DS-1H 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.
