All-tube amplifier of the Studio JTM Series The Marshall Studio JTM ST20H top unit is based on the famous Marshall JTM45 – also called Plexi – and makes the classic sound of the very first Marshall amplifier from 1962 now also available at low volumes. For a flexible tonal design, the guitar amplifier has the classic four inputs for both channels and a 3-band tone control with additional Presence control. Via the standby switch, the Marshall Studio JTM ST20H offers two different power levels: In Low mode, the power is limited to 5 watts to provide rich sounds for recording purposes or for small living room gigs. In High mode, on the other hand, the amp draws its full power of 20 watts from two 5881 power amp tubes. Unlike the original, the Marshall Studio JTM is equipped with a convenient DI output and an additional effects loop, but on the visual level, it remains true to the original in every respect with the historically correct ‘Coffin’ logo and classic Fawn Fret.
