Ampeg

Ampeg is an American manufacturer of musical instrument amplification equipment, best known for bass amplifiers. Founded in the mid-20th century, the company established a reputation for rugged construction and distinctive tone that helped shape electric bass performance. Ampeg's product line has included guitar amplifiers, speaker cabinets, and related accessories, but the company is most closely associated with bass gear.

Among its most influential products are the B-15 bass amplifier, a compact, tube-powered combination that became a studio and stage staple; the SVT head, introduced in the late 1960s, a high-powered all-tube amplifier that became a signature sound for many players when used with large cabinets; and the Portaflex series, portable bass rigs featuring a fold-out or detachable cabinet design that aided road use and speed of setup.

Across its history, Ampeg has undergone various ownership and manufacturing arrangements, with production continuing to evolve and some lines reissued to meet modern players' needs. The brand remains a touchstone for classic bass tone and is frequently cited in discussions of bass amplification history.
