Marshall Studio JTM ST20H Head

Don’t let its size fool you, the superb all- valve tone of the Marshall Studio JTM packs a punch. Creating a sound that defined a generation, the JTM ST-20H delivers the legendary loud blend of crunch and clean recognised the world over.

Like the original 30W head, the Studio JTM ST-20 Head Amp is loaded with two ECC83 preamp valves, two 5881 power amp valves and one ECC83 phase splitter, taking you right back to the dawn 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 range 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.
