The amplifier that saw the birth of Marshall has returned. Experience the renowned JTM sound in a smaller form factor, delivering the cherished power Marshall is known for. The JTM makes a delightful addition to the Studio series, granting musicians an authentic, velvety, and tube-driven breakup at reduced levels, ideal for both home and studio applications.

Similar to its original 30W predecessor, the Studio JTM houses a duo of ECC83 preamp valves, two 5881 power amp valves, and one ECC83 phase splitter. Retaining the same level of control and versatility as earlier models, the Studio JTM unlocks a realm of all-valve tonal possibilities simply by connecting the two channels. With the added convenience of power switching, effortlessly toggle between 20W and 5W, while the presence of two loudness controls allows for playing at any desired volume. Furthermore, modern enhancements such as a DI out and FX loop have been incorporated, propelling the JTM into the present era.

Given its remarkable legacy, it comes as no astonishment that the JTM boasted an impressive roster of esteemed owners, including trailblazers like Jimi Hendrix, Angus Young, Joe Bonamassa, and Gary Moore, among others. Countless individuals have been captivated by its mesmerizing tone, whether encountered live on stage or within the confines of a recording studio.
