MXR · pedal
The MXR ZW44 Berzerker Overdrive is Zakk Wylde's signature overdrive pedal delivering powerful, cutting overdrive with exceptional definition and screaming sustain. The pedal features three straightforward control knobs: Gain for distortion level, Tone for overall EQ control, and Output for drive level management. The circuit enables a wide range of overdrive flavors from bluesy breakup through distinctive MXR crunch to full-on saturated overdriven sounds. The true tonal wonder lies in the Gain knob's responsiveness, enabling players to achieve everything from subtle drive coloration to aggressive, full saturation within a single pedal. Users report bone-crunching sound quality and exceptional pinch harmonic definition.
