The Marshall Studio JTM Series ST20H amplifier head features a compact, single-channel design and serves up a solid range of vintage JTM-style sounds. Loaded with ECC83 preamp tubes and 5881 power amp tubes, this 20-Watt guitar amp head can deliver classic crunch as well as tight cleans, and can even be toned down to a 5-Watt output as needed.

The ST20H Studio JTM: A Superb UK-Built Pedal Platform

Equipped with an effects loop, this amp head is happy to process your favourite effect pedals and, while the housing is a bit more compact compared to the original JTM heads, the whole thing is skilfully put together in the same UK factory as its esteemed predecessors. Finished with a DI output, the ST20H is ready for practice sessions and gigs alike.
