Rockman is a guitar electronics brand founded by Boston frontman and engineer Tom Scholz under Scholz Research & Development (SR&D), which Scholz established in 1980 in Massachusetts. The company first gained traction with the Power Soak, an inline amplifier attenuator, before introducing the product that defined the brand: the Rockman, a battery-powered, belt-clip headphone guitar amplifier launched in 1982. Engineered around tightly compressed, multi-stage analog circuitry, it packaged distortion, compression, equalization, chorus, and stereo echo into a portable unit and became closely associated with the polished, layered guitar tones heard on many mainstream rock and pop records of the 1980s.

The product line expanded through the decade with units such as the X100, the Soloist, the Ultimatum, and the rack-format Sustainor and Distortion Generator preamps, along with the Rockmodule series of half-rack effects that broke the original Rockman circuits into individual processors. Manufacturing was based in Woburn, Massachusetts. Tom Scholz used Rockman gear extensively in his own recordings with Boston, and the units appeared on records by a wide range of arena-rock and metal artists during the brand's heyday. As digital modeling overtook analog effects in the early 1990s, SR&D wound down, and in 1995 Scholz sold the Rockman line to Dunlop Manufacturing.

Under Dunlop, the Rockman name has continued through the MXR division, most visibly with the MXR Rockman X100 Analog Tone Processor, a stompbox-format reissue of the original X100's circuit and preset voicings. Vintage SR&D-era Rockman units remain sought after on the used market for their distinctive compressed clean and saturated lead sounds.

Rockman has 2 products cataloged on Equipboard, including Headphone Guitar Amplifiers.
