Marshall ST20H Studio JTM 20-/5-watt Tube Amplifier Head

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.

BUILT IN OUR UK FACTORY 

Meticulously crafted in our 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.

ALL-VALVE 

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