Product Description
The amp that started it all is back! Delivering the same iconic JTM sound, the ST20C Studio JTM combo gives you all of that marvellous Marshall mojo but in a new compact size with some modern enhancements up its sleeve. Offering authentic, smooth, and valve-driven break-up at lower volumes — the Marshall ST20C is perfect for home or studio use, yet its superb all-valve design and 12" Celestion Creamback speaker packs a serious punch for live use too!
Classic Marshall Crunch, Contemporary Refinements
Like the original 30W head, the Marshall Studio JTM is loaded with two ECC83 preamp valves, two 5881 power amp valves and one ECC83 phase splitter — taking you right back to the renaissance of rock 'n' roll. The Studio JTM also offers the same control and versatility as older models, where simply patching the two channels together opens up a world of tonal possibility.
Handy power switching has been added to allow you to change effortlessly between 20W and 5W modes, with two loudness controls meaning that you can play as loud as you like! Marshall have really gone the extra mile for modern musicians by integrating features such as a DI output and FX loop too, bringing the JTM into the now!
Made in the UK
Handbuilt at Marshall's world-class factory in Bletchley, England, the ST20C Studio JTM features finger-jointed cabinets, hand-welded chassis, hand-soldered potentiometers and valve bases, and the highest quality componentry. Adorned with period-correct aesthetics from the same metal, red enamel poured "coffin" logo, to its fawn fret complete with gold piping and beading — the Studio JTM beautifully nods to the swinging '60s.
"When I was demonstrated the Studio JTM, it took me back to my original JTM45, it was my sound… I feel like it is going to be something special." — Terry Marshall (son of Jim Marshall, the founder of Marshall and creator of the original JTM45).
