Hand-built and hand-wired in the U.S., the Ampeg Heritage B-15 delivers legendary tone in a design that truly lives up to the iconic standard set by inventor Jess Oliver 50 years ago. The Heritage B-15 features the circuit paths of both a 1964 and 1966 B-15, including classic Baxandall EQ controls and premium 6SL7 octal preamp tubes along with a bias switch, recreating each years’ distinctive bias methodology. The extremely high-quality flip-top cabinet features the legendary double-baffle design and houses a highly-researched, custom-designed 15" Eminence® driver. The Heritage B-15 is no mere tribute; it meets and exceeds the performance, look and tone of the legendary original, down to each and every component.
