Dunlop MXR M85 Bass Distortion
Dunlop · pedal
The MXR M85 Bass Distortion is a bass-specific distortion pedal from MXR by Jim Dunlop, designed to deliver high-gain distortion for electric bass while preserving low-end clarity and the clean bass fundamental through a wet/dry blend control. The M85 features two independent clipping modes, a dedicated blend control for mixing distorted signal with clean bass signal in any ratio, and a mid-boost control. The wet/dry blend is the critical practical feature, preventing the distortion circuit from eliminating the bass fundamental that full distortion engagement typically removes. The M85 covers classic rock bass grit through to modern metal bass distortion.
