Sometimes there's a thin line between what's an overdrive, what's a fuzz, and what's a distortion. The Marshall Shredmaster is definitely a full on 80's heavy metal distortion. But it also has the dynamics to pull off a very nice overdrive tone as well. The BYOC Shredder kit packs all the tone of the original pedal with volume, gain, bass, treble, and contour knobs into a box that is half the size of the original... and with true bypass. It's voiced to turn even a 6 watt open back combo with an 8" speaker into wall of Marshall full stacks. It's like having a JCM series in a box. Rock on!
