RMC Pickup Co. is a Berkeley, California company founded by Richard McClish, specializing in piezo-based acoustic and MIDI pickup systems for guitar. The company is best known for its Acoustic Gold saddle system, which uses individual string-contacting piezo sensors mounted under each saddle to deliver per-string output with strong signal, wide dynamic range, and minimal cross-talk between strings. That per-string isolation is what makes the system a common choice for hex-output and 13-pin MIDI guitar applications, where accurate tracking depends on clean separation of each string's signal.

McClish started the operation as a small custom shop building polyphonic pickups and related analog electronics, and the design caught on with luthiers and manufacturers building hybrid acoustic-electric and MIDI-ready instruments. Godin's MultiAc line was designed around the RMC system with integrated 13-pin output, and RMC pickups appear in installations for nylon-string, steel-string, archtop, and mandolin family instruments. The company also produces preamps, polydrive interfaces, and a range of saddle sets sized for traditional classical, flamenco, hybrid, and multi-string instruments.

RMC pickups have been used by jazz and fusion guitarists including Pat Metheny, John McLaughlin, Al Di Meola, and John Pizzarelli, among others working in idioms where amplified nylon-string tone or guitar synthesis play a central role.

RMC has 4 products cataloged on Equipboard, including Preamps, Wah Pedals, and Steel-string Acoustic Guitars. Their gear is featured by 3 artists, with the strongest followings in Rock. Notable users include Adrian Belew, Joe Walsh, and Andrew Watt.
