Marshall Studio JTM ST20H 20 Watt Guitar Head Key Features
- Classic JTM Sound - The Studio JTM stays true to its heritage, delivering the same iconic JTM sound that defined a generation of rock'n'roll. With two ECC83 preamp valves, two 5881 power amp valves, and one ECC83 phase splitter, this all-valve amplifier takes you back to the golden era of rock.
- Power Switching - Offering both 20W and 5W power settings, the Studio JTM allows you to dial in the right amount of volume for any situation. Whether you're cranking it up for a gig or keeping it low for studio sessions or home use, this amp has you covered.
- Versatility - The Studio JTM features four separate inputs on a single channel, allowing for a wide range of tonal possibilities. With High, Treble, and Normal loudness controls, you can sculpt your sound to perfection.
- Modern Additions - Marshall has brought the JTM into the present with added features like a DI output and an FX loop, enhancing its versatility and making it suitable for modern recording and performance needs.
- Craftsmanship - Hand-built at Marshall's renowned factory in Bletchley, England, the Studio JTM exemplifies the highest quality craftsmanship. With finger-jointed cabinets, hand-welded chassis, and hand-soldered potentiometers and valve bases, this amp is built to last.
- Period-Correct Aesthetics - Paying homage to its 60s roots, the Studio JTM features period-correct aesthetics, including the metal red enamel poured "coffin" logo, fawn fret with gold piping and beading, and other vintage-inspired design elements.
