Gallien-Krueger

Gallien‑Krueger (GK) is a U.S. bass‑amp legend founded in 1968 by engineer Bob Gallien, pioneering powerful solid‑state designs and bringing the iconic dry “growl” tone to renowned models like the 800RB and 400RB. They remain innovators, first with bi‑amping, active 4‑band EQ, and channel‑switching heads, and have continued to evolve with modern Fusion S and RB Legacy series, all built for rugged, road‑ready reliability and used by top pros like Flea and Duff McKagan.
