The Rockman is a headphone guitar amplifier.
The original Rockman was developed and built by Scholz Research & Development, Inc., a company founded by Tom Scholz, who is also the founder and a key member of the rock band Boston.
Scholz Research & Development was sold to Dunlop Manufacturing, Inc. in 1995. Dunlop continues to manufacture the Rockman Ace, and Tom Scholz's signature still appears on the unit.
The Rockmans inspiration may have been from early designs produced by a paging and sound reinforcement company, first used by the band Boston in 1976. The original design shows the core technology (Reticon SAD 1024 Analog Delay ICs) that was used in the Rockman product years later.
