Peavey Musician 400 Series Bass Head

The Peavey 400 Series Musician Bass Head is a workhorse from the golden age of Peavey—built in the USA in the late ’70s/early ’80s and designed to deliver serious clean power and reliability. Rated at a massive 210 watts RMS @ 4 ohms, this solid-state head was a favorite among bassists, steel players, and even guitarists who needed headroom for big stages.

It features Peavey’s distinctive two-channel design with flexible EQ, bright/deep voicing, and plenty of volume on tap. Known for being nearly indestructible, the Musician Bass Head is part of the legendary 400 Series that put Peavey amps on the map for gigging pros.

Whether you’re chasing vintage solid-state bass tones, a platform for pedals, or just want a bombproof amp with a ton of clean headroom, this Peavey delivers.
