Used Mad Professor Blueberry Bass Overdrive Bass Effect Pedal

Used and in good condition, the Mad Professor Blueberry Bass Overdrive is a trusted choice for bassists seeking to enrich their tone with warm, creamy overdrive—without losing clarity in the low end. Designed with bass players in mind, it features intuitive Volume, Drive, and Nature controls that make it easy to shape your sound, whether you’re aiming for subtle grit or a more saturated, vintage-style breakup. Known for its natural tube-like response and dynamic feel, this pedal delivers consistent performance ideal for blues and rock players alike. Its compact, road-ready build fits seamlessly into any pedalboard, while true bypass ensures your tone remains untouched when the effect is bypassed. Powered by a standard 9V supply (not included), it’s a reliable and valuable addition to any bass setup.
