The Ampeg Rocket R-12R was a tube-driven combo amplifier from the early 1960s, featuring a 12-inch speaker and reverb, aimed at guitar players seeking a compact American tube sound. It used a pair of 6V6 output tubes for approximately 18 watts of power, with 12AX7 tubes in the preamp. The Rocket series was Ampeg's answer to the growing guitar combo market, offering warm clean tones with spring reverb in an affordable, portable package.
