Product details
The RockJam RJSP01 Universal Sustain Pedal is built to deliver the expressive control of a traditional piano pedal while offering the flexibility modern musicians need. With its sturdy chrome footplate and responsive spring action, it recreates the natural weight and rebound of an acoustic piano pedal, giving every note a richer, more authentic sound. One of its standout features is the integrated polarity switch, which eliminates the frustration of compatibility issues. Since different keyboards interpret pedal signals differently, many pedals work only with specific brands. The RJSP01 solves this problem with a simple switch: flip it once, and you can use it seamlessly with nearly any digital piano, synthesizer, or keyboard equipped with a 1/4″ input. This means you can move between instruments, upgrade your setup, or share gear without ever worrying about your sustain pedal holding you back. Another thoughtful detail is the extra-long 5.9-foot cable. Unlike shorter cords that limit positioning and force awkward setups, this generous length allows you to place the pedal exactly where it feels most comfortable, whether you’re practicing in a tight home studio, performing on stage, or connecting to a keyboard tucked deep into a stand. It also reduces strain on both the cable and jack, ensuring long-lasting reliability. Combined with a non-slip rubber base that keeps it firmly in place, the RJSP01 offers both performance and practicality. Its sleek, durable design makes it an essential companion for musicians who want expressive control, hassle-free compatibility, and freedom of movement in their playing experience.
