This manual covers the Peavey 6505 MH, a 20 W all‑tube guitar amplifier that delivers authentic tube tone in a compact micro‑head format. It explains safety precautions, power requirements, and the functions of the front‑panel controls, footswitches, and rear‑panel connections.
Key sections include detailed descriptions of the front‑panel channel and gain switches, the power‑on and standby sequence, the impedance selector, speaker defeat and headphone outputs, the MSDI and USB recording interfaces, and the built‑in effects loop. The specifications page lists electrical and mechanical data, while the warranty section outlines coverage for U.S. and Canadian customers.
