The Rockman A12-50 guitar amp is a rare, 50-watt solid-state 1x12 mono combo guitar amplifier created by Tom Scholz's Scholz Research and Development (SR&D). Tom Scholz is the guitarist of Boston. Released shortly before SR&D was acquired by Dunlop Manufacturing, it is estimated that only about 500 units were ever made.

Autographed.

Key Features & Specifications

• Power & Speaker: 50-watt solid-state design featuring an original 12-inch Celestion speaker.
• Channels: Two-channel setup offering a Clean channel (with Gain, Semi-Clean switch, and Volume) and a Distortion channel (with Gain and Volume), plus Pre EQ controls for Bass, Mid, and Treble.
• Built-in Circuitry: Often associated with the Rockman Ultimatum Distortion tone, though it notably lacks the built-in chorus and reverb found in other Rockman units.
• Side Brackets: Designed to integrate with Rockman modular gear using side-mounted mounting brackets to hold additional effect modules directly on the chassis.
