Description

Boost your tone with this used MXR M133 Micro Amp Preamp pedal in good condition, a compact gain booster that adds up to +26 dB of clean, full-bodied volume for solos, level matching, or pushing an amp into natural breakup. Simple single-knob control makes dialing in the right lift fast and musical, while the rugged MXR housing is built for gigging. Standard 1/4" input/output connections and true-bypass-style switching keep your signal clear.
