Up for sale is the legendary, budget-friendly MXR M66 Classic Overdrive in its classic green enclosure.This pedal delivers warm, tube-like crunch and a fantastic mid-range boost that cuts right through the mix. Unlike other budget overdrives, the M66 retains your low-end response, making it perfect for boosting a tube amp or adding smooth grit to your clean channel.

The Hidden Secret:
For the tone chasers out there, this pedal features the famous internal slider switch on the circuit board. Flipping this switch changes the clipping circuit, instantly transforming the pedal into the more aggressive MXR Zakk Wylde Wylde Overdrive spec! [1]

Condition & Features:

  • Controls: Output, Tone, and Gain.
  • Build: Rugged, compact MXR metal enclosure.
  • Power: Runs on a standard 9V battery or 9V DC power supply (not included).
  • Condition: [Insert condition here, e.g., Excellent condition, minor pedalboard tape residue on bottom, fully tested and 100% functional]. [1, 2, 3, 4, 5]
