Marshall JTM ST20C 20 Watt Combo Made in the UK
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.
ICONIC SOUND IN A COMPACT SIZE
The Studio JTM meticulously recreates the legendary tones of the original JTM recognised all over the world, now in a compact size that makes travelling and gigging a breeze. The Studio JTM delivers a blend of clean and crunch, the same tones that sprung Marshall to the forefront of rock ‘n’ roll in the 60s.
AUTHENTIC VINTAGE TONE
The Studio JTM range features classic G12M-65 Creamback Celestion speakers that were first developed in the mid-sixties. With such a rich heritage, it’s no surprise that the JTM had a wealth of famous owners, including pioneers such as Jimi Hendrix, Angus Young and Gary Moore.
POWER REDUCTION TECHNOLOGY
The Studio JTM has been expertly crafted to adapt to any situation using built-in power reduction technology. Swap between 20W and 5W at the flick of a switch and let the sound of a generation steal the show, whether you’re playing at home, or on stage.
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.
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.
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.
HANDMADE IN THE UK
Built in the same UK factory just like the original, the ST20C is adorned with period-correct aesthetics – from the same distinctive, solid metal, red enamel poured “coffin” logo, to its fawn fret complete with gold piping and beading, the ST20C beautifully nods to the 60s.
