The MXR Berzerker Overdrive, formerly known as the Wylde Overdrive, is a scathing overdrive pedal that's essential for crafting the thick tones of Zakk Wylde. Separate input and output controls allow for a range of gain staging possibilities any tone at any volume, whether you're just looking for a little push out your clean tube amp or sending an already dirty amp into submission. A single-knob tone control shapes your sound in a way that takes most guitar amps several controls to round out this easy-to-use pedal that deserves a spot on your hard rock pedalboard
