.The magic of the Distortion Plus is the abilty to schizophrenically pull off various personalites of overdrive, distortion, or fuzz depending on the rig you're running through. From the scooped metal madness of Randy Rhoads to the creamy streamlined crunch of Sugar, this box, uhhh, molds itself to the your own equipment and style. MXR spent some quality time and really voiced this one well. So much so that the absense of the typical tone knob isn't even missed. By twisting a combination of the gain and level knobs you can effortlessly nail the classic valvey chime of ACDC, the deep dark tone of Van Halen, or the relentless raspiness of Rage Against The Machine.
