Rare Earth Music LLC is a Salt Lake City, Utah-based company that manufactures the Earthboard, a patented pedalboard system that uses rare earth magnets and a steel-rail design to both secure and power effects pedals. Founded by Mark Bradley and Kym Bradley, the company debuted at Summer NAMM 2018 and is veteran-owned with all products made in the USA.

The Earthboard's core innovation is its magnetically-powered rail system, which eliminates traditional adapter cables and wall-power dependency. Pedals attach via the company's patented "Gravity Boot" docking system and receive power through the rails from either a built-in rechargeable battery or a 3-amp AC adapter. The design aims to reduce cable clutter, hum, and noise interference while allowing musicians to quickly swap or rearrange pedals of any size. The original Earthboard launched in configurations for 5, 7, or 11 standard-sized pedals, followed by the next-generation EBII and EBII-SR models featuring a lighter, more durable docking station and built-in cross-board patch cables. Accessories include the ISO-Boot for powering pedals with non-standard voltage requirements.
