Marshall ST20H Studio JTM 20W Tube Amplifier Head

Description

The amp that started it all is back. The same iconic JTM sound, but more compact packing the power you know and love from Marshall, in a new compact size. The JTM is a welcome addition to the Studio range, offering players authentic, smooth, and valve-driven break-up at lower volumes – perfect for home or studio use. Don’t let its size fool you, the superb all- valve tone of the Studio JTM packs a punch. Creating a sound that defined a generation the JTM delivers the legendary loud blend of crunch and clean recognised the world over.

Like the original 30W head, the 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 offers the same control and versatility as older models, where simply patching the two channels together opens up a world of all-valve tonal possibility. Power switching enables you to switch effortlessly between 20W and 5W and two loudness controls mean you can play as loud as you like. Features such as a DI out and FX loop have been added, bringing the JTM into the now.

Hand built at Marshall's world-class factory in Bletchley, England, the 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 60s.

Features:

  • This reissue painstakingly reproduces the legendary, warm, and smooth tone of the original Marshall JTM that inspired generations of musicians. 
  • The same iconic JTM sound, but more compact. The Studio JTM packs a punch while taking up less space than the original.
  • Swap between 20W and 5W at the flick of a switch and let the era-defining sound of the JTM steal the show, whether it’s playing at home, or on stage.
  • Expertly crafted in Bletchley, England, this iconic British-built amp effortlessly captures the Marshall spirit.
  • Faithfully recreated, the Studio JTM is beautifully crafted with iconic touches that hark back to the 1960s.
  • With a rich heritage of over 60 years, the JTM has had a wealth of famous owners, pioneers such as Jimi Hendrix, Angus Young, Joe Bonamassa and Gary Moore.
  • The Studio JTM is crafted with classic Creamback Celestion speakers, first developed in the mid-sixties.
  • Much like the original JTM, the Studio JTM has the ability to jump channels with a patch cable.
