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.
