The MXR Bass Synth, designed in collaboration with "low-end professor" and session bass guru Ian Martin Allison, is a creative powerhouse that transforms your bass into a groove-driven synth machine. It delivers everything from fat, vintage-inspired analog tones to deep, modern sub-heavy textures—all with incredible tracking, sustain, and tonal control. Loaded with thunderous sub-octave power, expressive envelope shaping, and lush modulation, this pedal channels the spirit of iconic bass synth tones from artists like Stevie Wonder, Parliament Funkadelic, and Nine Inch Nails while giving you the modern flexibility to craft your signature sound.Every control on the MXR Bass Synth is built for deep tone sculpting. The Sub Mix, Mod, and Envelope knobs let you blend layers of synth texture, from syrupy sweeps to pulsating motion. Mix, Cutoff, and Resonance controls refine your tone and focus. Voice and Shape buttons expand your sonic range, switching between harmonically rich oscillators and classic synth waveforms like triangle, sawtooth, and square. For instant inspiration, eight artist-designed presets from Ian Martin Allison put legendary tones at your fingertips, inspired by hits like “Chameleon,” “Sledgehammer,” and “Thriller.” Powered by a 9V center-negative supply (no battery option), the MXR Bass Synth drops stage-ready synth power directly on your pedalboard, letting you reimagine your bass as a full-spectrum funk, rock, or electronic instrument.MXR MB301 FeaturesDesigned in collaboration with session ace Ian Martin Allison, delivering studio-grade bass synth tonesTransforms your bass into a groove-driven synth machine with fat analog textures and deep modern sub-bassFeatures Sub Mix, Mod, and Envelope controls for dynamic layering and expressive movementMix, Cutoff, and Resonance knobs provide precise tone shaping and control over synth characterVoice and Shape buttons toggle between rich oscillators and classic waveforms (triangle, sawtooth, square)Includes eight artist-designed presets inspired by iconic bass synth tones from Stevie Wonder, Parliament Funkadelic, Nine Inch Nails, and moreOffers incredible tracking, sustain, and tonal control across diverse playing stylesPowered by a 9V center-negative supply (no battery) for reliable pedalboard integrationChannels classic synth vibes from tracks like “Chameleon,” “Sledgehammer,” and “Thriller” while offering modern flexibilityCompact, rugged MXR design ready for stage, studio, or experimental sound design MXR MB301 Bass Synth Pedal.
