The DOD 250 was a sibling of the Distortion+, but slightly smoother and more “amp-like.” Yngwie Malmsteen’s use made it legendary, and it inspired boutique descendants like the MXR Custom Shop Dyna Comp reissue and the Ceriatone Horsebreaker. It’s the root of many modern “preamp-style” overdrives that aim to add grit without too much coloration.
