Kurzweil AMS-KP-1H Piano-Style Half-Damper Pedal

The Kurzweil AMS-KP-1H is a single sustain pedal built for players who demand more nuance from their electronic keyboard performances. Unlike standard switch-style pedals that only register fully on or fully off, the KP-1H supports half-damper operation, allowing you to control the degree of sustain by how far you press the pedal down. This mirrors the behavior of an acoustic grand piano's damper mechanism, where partial pedaling blends notes with a subtlety that binary pedals simply cannot achieve.

The pedal features a piano-style chassis that sits firmly on the floor, providing the kind of weighted, grounded feel that keyboard players expect during extended sessions. Connection is handled through a 1/4-inch stereo (TRS) plug, which carries the continuous control signal required for half-damper recognition. At 9.65 x 3.94 x 3.35 inches, it's compact enough to tuck into a gig bag alongside your other accessories. The key consideration before purchasing is compatibility: your keyboard or digital piano must explicitly support half-damper or continuous pedal input over a TRS connection to unlock the graduated sustain that makes this pedal worthwhile.
