The Iconic "Plexi" Sound, Scaled for Today’s Stage and Studio.
Experience the legendary roar of the 1959 Super Lead without the 100-watt footprint. This preowned Marshall Studio Vintage SV20H head captures the timeless "Plexi" era elegance and raw tonal power in a compact, portable 20-watt design. Handcrafted in the UK, the SV20H delivers the same warm blues cleans and saturated rock grit that defined generations of guitar legends.
This preowned head is in excellent overall condition, the tolex is peeling slightly (see photos).
Whether you're recording in a home studio or playing a club gig, the built-in power reduction technology allows you to flick a switch and drop from 20W to 5W, giving you cranked-tube saturation at manageable volumes. With four separate inputs for channel jumping and a transparent series effects loop, this head offers the authentic vintage Marshall experience with the modern flexibility today's player demands.
