Faithfully recreating the sound and look of a pedal that helped define '90s distorted guitar playing, the ShredMaster from Marshall Amplification is a high-gain distortion pedal that delivers swathes of ground-shaking gain, ideal for saturated rhythm sounds and searing solos. Famously used by many '90s guitarists, such as Johnny Greenwood of Radiohead, Alex James of Blur, Kevin Shields of My Bloody Valentine, and many more, the ShredMaster has long been favored for creating walls of cascading distorted guitar, and this exactly replicated pedal, down to the case design and circuitry, provides all the same power in an authentically UK-manufactured steel case that will survive for years of touring and studio work.

The ShredMaster sports plenty of tone-shaping control via dedicated bass and treble control knobs as well as a contour control that changes the character of the midrange response and simultaneously enhances the treble and bass frequencies. You can also set pre-distortion gain levels as well as output volume. A red LED above the footswitch becomes illuminated when the effect is active.
