Get to know them!

Ask any amp aficionado which amplifier led the rock revolution, and you’ll get a near-unanimous response: the Marshall 1959 Super Lead. The SV20H Studio Vintage takes that legendary tone and packs it into a 20-watt head. Plug in, and you’ll experience saturated blues grit and biting leads — the iconic Plexi tone. The Studio Vintage has plenty of player-friendly features on tap, such as four separate inputs, high- and low-sensitivity loudness controls, a 3-band EQ with Presence control, an effects loop, and a DI output. Worried about disturbing your neighbors? Don’t — the Studio Vintage’s power reduction circuit takes its wattage down to a bedroom-friendly five watts. If you want cranked Plexi tones from a compact, studio-sized amp, the Marshall SV20H Studio Vintage absolutely nails it.

1959 Plexi — the amplifier that led the rock revolution

The Marshall SV20H Studio Vintage is a low-watt version of Marshall’s 1959 Super Lead, a.k.a. the coveted Plexi. Townshend, Clapton, and Hendrix, to name a few, all played the 1959 Super Lead. This is the iconic amplifier that defined the sound of rock ’n’ roll for generations of guitar players, and it can be seen on countless stages of yesterday and today, including Woodstock. If you want the tone that inspired generations of iconic guitarists, plug into a Studio Vintage — it delivers true-to-life Plexi tone!

Loaded with all the player-friendly features you need

Consider yourself lucky, because the Marshall SV20H Studio Vintage sports features not found on the original 1959 Super Lead. An effects loop makes integrating your pedals and external processors a breeze. Attaining cranked tones at listenable volumes is a breeze thanks to a power reduction circuit. You also get a DI output for easy recording or routing to a PA. The guitarists at Sweetwater value the Studio Vintage’s modern flexibility almost as much as we appreciate its classic tone.
