Sometimes there is 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. The BYOC Shredder kit packs all that original tone with volume, gain, bass, treble, and contour knobs in a box that is half the size of the original with true bypass. It's like having a later model Marshall full stack in a box.
