Product Description

The Marshall Studio JTM amp is the perfect choice for guitarists who seek a powerful, yet portable amp that’ll take your sound to the next level. This historic amp is back and better than ever! Enjoy the same iconic JTM sound, but in a more compact form. While small in size, this remarkable amp uses all-valve power to offer a big, powerful sound. Everyone will recognize the loud blend of crunch and clean that made Marshall classic.

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 our world-class factory in Bletchley, England, the Studio JTM features fingerjointed 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.
