Boost your tone with this used MXR M133 Micro Amp Preamp pedal in great condition. This compact, all-analog clean boost adds up to +26dB of gain to push an amp, brighten solos, or fatten single-coils without changing your core sound. Simple single-knob control makes dialing in the perfect level fast, while the rugged MXR enclosure is built for gigging. Runs on a 9V battery or standard 9V DC adapter.
