Ampeg Heritage 50TH Anniversary SVT USA All-Tube 300W Bass Head

From well-informed amateurs to elite professionals, no amp enjoys as passionate a fan base as the Ampeg SVT. For this new SVT, Ampeg surveyed its loyal customers to ensure that the design met and surpassed their wishlist. That's why the Heritage 50th Anniversary SVT offers two discrete preamp channels that duplicate the revered tone from the amp'S most desirable eras: the original 1969 Blueline SVT and the mid-70s Magnavox design - and the two can be jumped together. Specially sourced and matched Ampeg Super Valve 6550 tubes complete the picture, while the period-correct graphics and fonts and etched panel firmly reinforce the Heritage 50th Anniversary SVT amp head's vintage aesthetic, contemporary features like a newly enhanced balanced XLR DI output, user biasing, whisper-quiet fan, and Neutrik speakOn speaker outputs place its construction firmly in the present, the Heritage 50th Anniversary SVT is the flagship amp from the Ampeg range.

AMPEG HERITAGE 50TH ANNIVERSARY SVT

INDUSTRY-STANDARD ALL-TUBE BASS AMP

The Ampeg® SVT® is more than just a bass amp—it sparked a revolution. When it debuted in 1969, deafening walls of full-stack guitar amps were eating bass players alive. Knowing that big bass volume required big power, Ampeg designed the most sophisticated amp of its day: the 300-watt SVT. Finally, balance returned to the stage and with it a generation of iconic bass-forward music was born. That singular Ampeg spirt of innovation and ingenuity is alive and well in the Ampeg HeritageTM 50th Anniversary SVT bass amp. Designed to honor the unrivaled SVT legacy, the Heritage 50th Anniversary SVT distills the legendary amp’s most celebrated circuits into a single stage-ready head with a host of must-have modern technology and elegant vintage aesthetics. It truly is the SVT for the 21st century.
