The ShredMaster is the high-gain pedal in the trio Marshall released in 1991 with the Bluesbreaker and Drivemaster. It is a conventional distortion pedal with Gain, Bass, Contour, Treble and Volume controls in a black, wedge-shaped metal case. Poor sales ended the run within a few years, and Marshall reissued it in 2023.
The Marshall 1960A JCM900 is Marshall’s designated main 4x12 cabinet—widely used, widely modified, and widely criticised. Its four Celestion G12T75 speakers deliver 300 watts of aggressive, scooped tone. Birch plywood construction meets an MDF back panel. Rear-panel impedance and stereo switching add flexibility. But air leaks at the seams. Joints feel insecure. Plastic handles flex under load. It excels only where harsh highs and tight lows serve metal—but fails jazz, grunge, and any genre demanding warmth or low-end authority.
The Marshall 2203 JCM800 Master Volume Lead is a tube guitar amp head introduced in 1981 and produced until 1989. It delivers aggressive, mid-forward distortion at manageable stage volumes — but offers no clean headroom, no effects loop, and no modern conveniences.
The Marshall Guv'nor is a no-compromise analog distortion/overdrive pedal. It gives guitarists direct, unmediated access to Marshall-style grit through five physical controls. It refuses modern conveniences: no USB, no rack ears, no presets. It was discontinued in 2023.
The Marshall JCM900 is a series of valve guitar amplifiers produced between 1990 and 1999, with some models reissued from 2003 onward. It was built for guitarists needing high-gain distortion and built-in reverb in a professional touring and studio context.
The Softube Marshall JMP 2203 is a software amp simulator in the Amp Room series. Softube made it. It carries the Marshall JMP 2203 name. It belongs to the Software Amp Simulators category.
The Marshall Silver Jubilee 2555 is a software amp simulator by Softube. It belongs to the Amp Room series. It has no published technical specifications. It is not hardware. It is not a standalone application. It is a plugin for digital audio workstations that host Amp Room.
The Marshall Bluesbreaker is Models 1961 and 1962 — Marshall’s first combo, built from 1964/65 to 1972. It is the JTM45 circuit in an open-backed cabinet. It delivers aggressive, responsive overdrive with no master volume, no clean headroom, and no flexibility — and that is precisely what made it essential.
The Marshall Super Lead is a 100-watt guitar amplifier head made by Marshall between 1966 and 1981. It was developed in response to player demand for higher output than the earlier JTM45. Its distortion arises solely from overdriving its EL34-based power amp section at high volume. It has two channels and four inputs but no master volume. Its core character is bold, midrange-heavy, and bright — delivering the foundational 'Marshall crunch' sound of 1970s rock.
The Marshall JTM45 is Marshall's first guitar amplifier, prototyped in 1962 and produced from 1963. It was developed as a British alternative to Fender amplifiers, using a modified Fender Bassman circuit with a 12AX7 preamp valve, Celestion speakers in a closed cabinet, and a modified negative feedback circuit that altered harmonic content. Its name reflects Jim and Terry Marshall and its 45-watt RMS rating.
The Marshall Major is a 200-watt guitar amplifier built from 1967 to 1974. It was designed to produce more volume and clean headroom than Marshall's other amplifiers like the Super Lead. The 200 had only three controls on the front panel and used a preamplifier circuit that was closer in design to a hi-fi amplifier rather than a guitar amp. In 1968, Marshall updated the 200 with a typical EQ compliment of treble, middle, bass, and presence controls, and it was now named the Major. This tone stack—which was passive compared to the 200's active controls—was placed between the second and third gain stages created using ECC83 (12AX7) preamp tubes. Ritchie Blackmore of Deep Purple and Mick Ronson of David Bowie's band are frequently associated with the Major.
