Marshall JTM 1962HW Super Tremolo 'Bluesbreaker' - UK 2015

Here is a 2015 Marshall JTM 1962HW Super Tremolo, a hand-wired reissue of the legendary Bluesbreaker-style amplifier that defined the early Marshall sound and was famously associated with Eric Clapton during his time with John Mayall & the Bluesbreakers. Part of Marshall’s Handwired Series, this model is designed to faithfully recreate the tone, feel, and response of the original 1960s circuit while offering the reliability of modern construction.

The “HW” designation refers to its handwired, point-to-point construction, using traditional assembly methods that many players associate with enhanced clarity, responsiveness, and harmonic depth. The Super Tremolo version expands the original design with a lush, vintage-style tremolo circuit, adding an additional layer of movement and texture to the classic Marshall voice.

This model is powered by two KT66 power tubes, supported by a GZ34 rectifier and four ECC83 (12AX7) preamp tubes, delivering rich headroom, smooth breakup, and the dynamic compression that defines the classic Bluesbreaker tone. It excels at producing warm, touch-sensitive overdrive that responds beautifully to picking dynamics and guitar volume changes.

Speaker configuration consists of two 12” Celestion G12M-25 Greenback speakers, widely regarded for their warm midrange, smooth top end, and classic British voicing. Together, they complement the circuit perfectly, producing the iconic “Bluesbreaker” tone—creamy, expressive, and harmonically rich.

Built to a high standard with premium components, the 1962HW is a robust, road-ready amplifier that also benefits from easier long-term serviceability due to its handwired design. It delivers both vintage authenticity and modern dependability in a single package.
