The MXR overdrive will give any rig as much extra bite as you need while preserving your existing tonal dynamics. With MOSFET clipping 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, featuring 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 it sounds simply sublime when used to rev up a tube amp that’s just about to cross the line.
