Ampeg is a legendary manufacturer of bass amplifiers and musical instrument accessories, renowned for the classic SVT tone and Portaflex series.
Ampeg is a distinguished American manufacturer of musical instrument amplifiers, celebrated specifically for its contributions to bass amplification. Founded in 1946 by Everett Hull and Stanley Michaels as "Michael-Hull Electronic Labs," the company derived its name from Hull’s "amplified peg" pickup design for upright basses. Throughout the decades, Ampeg has defined the sound of rock and roll with iconic products like the Portaflex "flip-top" combos and the powerful SVT (Super Valve Technology) amplifier heads, which became the industry standard for large-stage performance.
Today, Ampeg operates as a brand under the Yamaha Guitar Group, continuing to produce high-quality tube and solid-state amplifiers, speaker cabinets, and effects pedals. Whether for practice, studio recording, or stadium tours, Ampeg gear is prized by musicians worldwide for its rugged durability, vintage aesthetic, and signature deep, punchy tone.
