Rockbox Electronics is a San Jose, California-based boutique pedal company founded by Chris Campbell, a former Marketing Director at Dean Markley Strings who has been involved in guitar building and repair since 1971. Operating under the parent company Civilized World, Inc., Campbell drew on decades of consulting with professional musicians about their tone preferences to design a line of hand-built effects pedals that blend vintage and modern circuit topologies.

The company's flagship product is the Boiling Point overdrive/boost, which features a three-position diode selector for varied harmonic character and has earned a place on the pedalboards of guitarists like Elliot Easton, Richie Sambora, and Jimmy Vivino. The Rockbox lineup spans a wide range of drive and modulation pedals, including the Red Dog distortion, the Baby Blues vintage-voiced overdrive, the Brown Sugar high-gain solo pedal, the Super 763 (inspired by 1960s California amp tones), the Matador active preamp overdrive, the Dragonstone metal distortion, the Rainy Day analog chorus (available in guitar and bass versions), and the Pushy Galore compressor. Rockbox also offers the Abyssinia, an active bass preamp overdrive designed specifically for bass players.

Rockbox has 5 products cataloged on Equipboard, including Overdrive Effects Pedals, Distortion Effects Pedals, and Fuzz Effects Pedals. Their gear is featured by 4 artists, with the strongest followings in Rock, Metal, and Pop. Notable users include Steve Rothery, Pat Sheridan, and Rob Chapman.
