Used MXR Custom Shop GT-OD Overdrive (CSP-021) w/ Original Box

This MXR Custom Shop GT-OD is in great shape with only light signs of use — the kind of wear you'd expect from a pedal that spent its time on a board doing its job, not sitting in a drawer. The satin metallic green finish is clean throughout with no significant scratches, chips, or dings. All three knobs turn smoothly, the footswitch clicks solidly, the LED works, and both jacks are clean and secure. Everything functions as it should.

Includes the original MXR Custom Shop box, which has some minor shelf wear. No power supply included — runs on a standard 9V adapter (center-negative) or a 9V battery.

The GT-OD is MXR's take on a smooth, transparent overdrive — the kind that plays well with whatever amp you're already running rather than trying to replace its character. It cleans up nicely with your guitar's volume knob and stacks well in front of an already-cooking amp for lead tones with real sustain and harmonic content. Three knobs, no menus, no nonsense.

This is the CSP-021 Custom Shop version — the original run, before MXR folded the circuit into the standard M193 production model. The Custom Shop units are the ones that get specifically sought out on the used market, and for good reason. They were built in smaller quantities with MXR's Custom Shop component selection and hand-assembly standards. If you've been looking for one, you already know.
