Rooting back to the revolutionary 1969 Ampeg® SVT® bass amp, the classic character meets modern functionality in the Heritage 50th Anniversary SVT. Big bass volume to rise above guitar stacks, this amp uses 60's and 70's era Blue Line and Maganaovx style circuitry to deliver 300 Watts of power. Behind the elegant vintage aesthetics are several modern features for today's bassist including speakOn® outputs, a newly enhanced XLR DI output, user biasing, and spring-loaded side handles for easy travel. Honoring the unrivaled SVT legacy, the Heritage 50th Anniversary SVT encapsulates legendary circuit technology circuits into a modern, single, stage-ready head. For professional and amateur bass lovers, SVT50 brings the faithful and iconic SVT into the 21st century.
