    The Marshall Studio JTM guitar amp head is the perfect combination of classic tube-driven, Marshall tone and modern day portability and convenience. This iconic amplifier brings its classic sound to a much smaller size so you can fit into tight corners of your studio or house.

    For those who are used to the classic break-up of Marshall’s signature sound, the Studio JTM offers those same, clean, smooth tones that helped define a generation of rock. This top-of-the-line amplifier head is the perfect option for any guitarist looking to bring the “classic rock” sound into the modern era. The Marshall Studio JTM is the perfect addition to any guitarist’s arsenal, not just for home and studio recording, but for live shows as well.

    The JTM delivers the legendary loud blend of crunch and clean recognized the world over. Like the original 30W head, the Studio JTM is loaded with two ECC83 preamp valves, two 5881 power amp valves (tubes) 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.
