Product Description The MXR® MICRO AMP is a simple yet versatile clean booster pedal. It can boost the volume of your guitar or bass by up to 26dB, allowing you to increase the volume without altering your tone. It's perfect for boosting volume for solos or pushing the gain of your amp or overdrive to emphasize distortion. It's also useful as a buffer amp to compensate for high frequencies lost when using long cables, and for adjusting the volume difference between single-coil and humbucker pickups. I bought it around this summer and have only used it once!! If you'd like, I can also include the original box!
