Universal Sustain Pedal for Keyboards — 1/4" Jack with Polarity Switch

This sustain pedal ships as a single foot controller with an attached 63-inch (1.6-meter) cable terminated in a standard 1/4" (6.35 mm) mono plug for connection to the sustain jack on most digital pianos and keyboards.

The housing combines chrome-plated metal with a rubberized shell to resist wear and provide a modest level of protection against knocks and scuffs. The base is fitted with a slip-resistant rubber pad so the pedal remains stable on hardwood, carpet, or stage surfaces.

A built-in polarity switch lets you invert the pedal’s electrical action to match the expected behavior of different keyboards — useful when a particular instrument requires reversed polarity for sustain functions.

Designed for simple foot control: place the pedal on the floor in front of your instrument, plug the 1/4" jack into the sustain input, toggle the polarity switch if needed, and depress the pedal to hold notes. Response is immediate to give a natural playing feel.

Compact and lightweight, it’s intended as an affordable, universal solution for practice rooms, home studios, classrooms, and casual gigging where a reliable sustain pedal is required.
