The Peavey Roadmaster is a 160-watt all-tube guitar head from the late 1970s that stands as one of Peavey's most ambitious early tube designs, employing a six-tube 6L6GC output stage to generate massive clean headroom. Its circuit incorporates Peavey's DDT speaker protection circuitry and features separate lead and rhythm channels, making it one of the earliest high-power tube amps designed explicitly for multi-channel operation. The Roadmaster has become a collectors' amp valued for its unique combination of American brute power and early multi-channel architecture.
