The MXR Super Badass Dynamic O.D. will give any rig as much extra bite as you need while preserving your existing tonal dynamics. With MOSFET clipping diodes under the hood, this pedal's overdrive is a smooth purr that can be pulled back for a nice, clean boost or cranked into full gear for vintage high-gain grind. On the dashboard, a simple set of controls allows you to dial in the right sound for your setup, feature your classic Output, Tone, and Gain controls along with a Boost/Cut switch that allows you to bump up the overall level with a little extra midrange or drop everything down a notch. This pedal sounds killer on its own, but we think it sounds simply sublime when used to rev up a tube amp that's just about to cross the line. Step on the MXR Super Badass Dynamic O.D., and let that engine roar.
