Marshall ST20H Studio JTM 20 Watt Tube Guitar Amplifier Head

New

Power reduction from 20W to 5W at the flick of a switch

This amplifier provides you with the versatility to tailor your power output to suit your environment. Effortlessly select between 20W and 5W power output to seamlessly transition from the rehearsal room to the communal space and back again, without compromising on tone.

Inspired by the original JTM45

Reproducing the legendary, warm and smooth tones of the original JTM45, the Studio JTM range looks as good as it sounds. Let the all-valve, era-defining sound of the JTM steal the show, whether playing at home or on stage.

All-valve

This instantly recognisable tone is driven by two ECC83 preamp valves, two 5881 power amp valves and one ECC83 phase splitter.

BUILT IN THEIR UK FACTORY

Meticulously crafted in their Bletchley, England, factory the Studio JTM features classic Marshall touches such as a robust metal 'coffin' logo with golden piping and beading that pays homage to the 1960s. After extensive years of development, the Studio JTM delivers the timeless and velvety tones reminiscent of the original JTM.
