This used MXR Micro Amp Boost Pedal is in Fair Condition with stains, dings, and other signs of handling and use.

FROM MXR:

Adding a preset amount of gain with just a single control, the Micro Amp is a great way to boost your signal for lead work or adjust between two different guitars with unmatched output (i.e. humbuckers to single-coils). It can also provide a permanent boost in a long effects chain where signal drop off is a problem.
