Marshall Studio JTM ST20C Combo

The Undisputed Number One, Just Smaller!

The first JTM amplifier created a legendary sound that inspired generations of musicians. In its honor, the ST20C brings the iconic 60s Marshall tone, originally pioneered by Marshall, into a more compact format for today.

Whether at home, in the studio, or on the big stage—the ST20C adapts to deliver an exceptional tone in any situation, thanks to built-in power reduction technology that lets the player switch between 20W and 5W.

A Distinctive Sound

This reissue meticulously reproduces the legendary, warm, and smooth tone of the original Marshall JTM that inspired generations of musicians. The ST20C delivers the loud blend of crunch and clean that’s recognized worldwide.

Vintage Sound at Low Wattage

The ST20C is equipped with a Celestion Creamback G12M-65 speaker, ideal for producing the ultimate vintage tone. Switch between 20W and 5W at the push of a button to play at lower wattage without compromising sound quality.

Small But Mighty

Packed with the same vintage tones you know and love, just in a smaller package. The ST20C packs the power of a classic Marshall amp into a compact design.

Handcrafted In Great Britain

The ST20C is made in the same factory in Great Britain as the original and features a contemporary aesthetic—from the same distinctive solid metal and red enamel "coffin" logo to the deer-brown covering with gold piping and pearls—the ST20C is a beautiful nod to the 60s.
