Used MXR M81 BASS PREAMP Bass Effect Pedal

The used MXR M81 Bass Preamp is in excellent condition and offers studio-quality tone shaping in a rugged, compact housing. Designed for bassists who demand versatility, it features a 3-band EQ with sweepable midrange, an input gain control, and a separate output level, providing full control over your sound. The balanced XLR DI output and 1/4" out make it perfect for both stage and studio use. The M81 delivers clean boost and subtle drive without coloring your tone, and its true bypass switching ensures signal integrity when not in use. This pedal runs on a 9V battery or optional power supply and is an ideal addition to any bass rig looking for professional-grade preamp capability in a reliable and road-ready format.
