Modify your MXR Classic Overdrive. Mod service Only!
The MXR Classic Overdrive is a decent sounding pedal out of the box. Many people are unaware of the internal toggle switch that can engage the circuit to Zakk Wylde ZW44 specs. I relocate the switch to the side of the pedal to allow selection without removing the bottom plate. This is especially useful if you switch guitars / amps frequently - or in the recording studio where you want different tone options. I also upgrade the knobs and LED!
