> New from Ampeg: Heritage 50th Anniversary SVT head

To celebrate their 50th anniversary, Ampeg are releasing the Heritage 50th Anniversary SVT, which launched at the 2019 Summer NAMM Show last week. According to the producer’s description, the unit combines ‘the 1969 “Blue Line” and mid-1970s Magnavox-era circuits in one amp’, and at the same time features ‘must-have modern technology ‘.

Ampeg’s statement reads:

“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.”

The amp is handmade in the U.S.A. from durable top-shelf components, and it is not a reissue. It utilizes detailed, period-correct graphics and font, as well as such modern features as: a newly enhanced XLR DI output, user biasing, speakOn® outputs, spring-loaded side handles, and specially sourced and matched Ampeg Super ValveTM 6550 tubes.
