Transform your bass into a filthy funk machine with the MXR MB301 Bass Synth Pedal. This isn't just another effects pedal — it's your portal to intergalactic grooves and vintage analog-style vibes that channel the legendary synth bass sounds of Stevie Wonder, Michael Jackson, Parliament Funkadelic, and more.
Loaded with Features for Unmatched Sonic Exploration
Designed in collaboration with low-end professor and tone connoisseur Ian Martin Allison, this powerhouse pedal delivers thunderous sub-octave, expressive envelope, and lush modulation effects with killer tracking and sustain that'll make your bass lines bounce off the walls. The MB301 gives you the tools to craft monophonic synth tones that are nothing short of magical:
Eight Ready-to-Rock Presets: Skip the setup and jump straight into the groove with presets inspired by classic tracks like Michael Jackson's "Thriller," Herbie Hancock's "Chameleon," Peter Gabriel's "Sledgehammer," and Nine Inch Nails' "Head Like a Hole".
Three Distinct Waveforms: Choose your sonic weapon — smooth and subtle triangle waves, rich and aggressive sawtooth, or fat and punchy square waves.
Additional Oscillators: The Voice button adds harmonically tuned oscillators for complex, layered tones that'll make your bass sing in multiple dimensions.
Master Your Groove with Intuitive Controls
The MB301 puts serious sonic sculpting power at your fingertips without overwhelming you with complexity. Every knob has been thoughtfully designed to give you maximum tonal flexibility while keeping the interface player-friendly:
Sub Mix Control: Dial in exactly how much thunderous sub-octave gets blended with your main synth signal — go as fat and low as your speakers can handle.
Modulation Magic: The Mod knob takes you from subtle, musical motion to bold, mind-bending pulses that add liquid shimmer to your tone.
Envelope Response: Set your filter response anywhere from rubber band bounce to slow, syrupy sweeps that breathe with your playing dynamics.
Mix, Cutoff, and Resonance: The holy trinity of tone shaping lets you blend dry and wet signals, set filter cutoff frequency, and boost specific frequencies for extra punch.
Designed for True Bottomology Experts
For players who want to dig deeper into sonic exploration, the MXR Bass Synth offers advanced features that separate it from basic synth pedals. This isn't just about making weird noises — it's about crafting professional-grade synth bass tones:
Stereo Output Mode: Run the pedal in stereo for immersive, wide soundscapes that fill every corner of the mix.
External Control Options: Use off-board switches like the MXR Split + Tap or Tap Tempo Switch to cycle presets hands-free during performances.
Volume Pedal Integration: Connect a Volume (X) Series Pedal to blend setting configurations on the fly.
Advanced Parameters: Access additional oscillator and modulation mix controls, compression settings, and tracking styles for ultimate customization.
Prepare to Embrace the Bold
Whether you're replicating pop hits in a cover band, holding down the low end at church, or touring the world with your original material, the MXR MB301 Bass Synth Pedal gives you instant synth bass magic. It's time to get down on the one and let your bass lines lead the funk revolution.
