Category: Guitars, Amps, and Effects

The Marshall Studio JTM is a love letter to the amplifier that started it all — the original JTM45, Marshall’s very first production amp that set the template for British rock tone. Built in a compact, studio-friendly head format, the Studio JTM lets you access that authentic early Marshall sound at two power levels: 20 watts for stage use and 5 watts for studio and practice settings.

KT66 power tubes give the Studio JTM a distinctly different character from EL34-based Marshalls — rounder, more open, and with a softer, more dynamic breakup that cleans up beautifully when you roll back your guitar’s volume. It’s the amp tone that defined early blues-rock, and it remains one of the most musical and expressive amp voices ever created.

Key Features:
– 20-watt and 5-watt power modes for flexible studio and stage use
– KT66 power tubes for authentic early Marshall JTM character
– ECC83 preamp tubes for warm, dynamic preamp response
– Single channel with Volume, Bass, Middle, and Treble controls
– Series effects loop for integrating studio-quality effects
– High and Low input sensitivity options
– Compact head format — pairs with any Marshall or compatible cabinet
– Handwired for premium signal quality

For the professional guitarist who wants the authentic sound of rock’s earliest British amp in a practical, manageable package, the Marshall Studio JTM is an exceptional and historically significant amplifier.
