This is identical to the MXR Dookie pedal which is based on two modified Marshall amps that Billie Joe Armstrong has used since the Dookie album. The only differences are that the Dookie pedal has the Green Day artwork, and this MXR FOD has a three way mid range toggle switch that the Dookie pedal does not have. You can have the mids flat, you can boost them, or you can scoop the mids.

This pedal is in like new mint condition. No velcro or damage of any kind. Never gigged with. It comes with the box, the plastic bag it came wrapped in, an MXR sticker and the instruction booklet.
