The first JTM amp created a legendary sound that inspired generations of musicians. In honour of that, the ST20C brings the iconic 60’s tone that initially launched Marshall to the present day, in a more compact format.
Whether you’re at home, in the studio, or on the big stage – the ST20C can adapt to bring exceptional tone to any situation with built-in power reduction technology, enabling players to switch between 20W and 5W.
AN UNMISTAKABLE SOUND
This reissue painstakingly 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 recognised the world over.
SMALL BUT MIGHTY
Packed with the same vintage tones you know and love, just in a smaller package, the ST20C has the power of a classic Marshall amp in a compact design.
LOW-WATTAGE VINTAGE SOUND
Ideal for creating that definitive vintage tone, the ST20C is equipped with a Celestion Creamback G12M-65 speaker. Switch between 20W and 5W at the flick of a switch to allow playing at a lower wattage without compromising on tone.
