2023 Marshall ST20H Studio JTM 20W Tube Amplifier Head - Preowned

The Marshall Studio JTM captures the soul of Marshall’s earliest amps in a compact, gig-friendly format that still delivers authentic, harmonically rich British tube tone. This 2023 example is in excellent condition and comes to us on consignment from the original owner. From glassy, three-dimensional cleans to thick, touch-sensitive breakup, the Studio JTM nails the feel and response that made the original JTM legendary—without the size or volume constraints. A killer choice for players who want true vintage Marshall tone in the studio, at home, or on stage.
