Based on the vintage JMP 1959SLP which was the amp that defined classic rock tone, with its plexiglass panel seen on the 100W amps in the late 60’s. It was considered a sonic essential by many famous guitarists for its sheer power and tonal possibility. The Studio Vintage is available as a 20W head or combo.
The SV20H brings the classic tone of the 1959SLP straight to your home. Arguably the most famous amp of all time has been perfectly reinvented for today’s guitarist. Uniting the original all-valve sound with the choice to switch between 20W and 5W at the touch of a button, all packed into the definitive rock rig.
