MXR Unveils New Bass Synth Pedal in Collaboration with Ian Martin Allison
MXR®, a division of Dunlop Manufacturing, proudly announces the launch of the MXR Bass Synth Pedal, a bold and versatile addition to the MXR Bass Innovations line. Developed in close collaboration with acclaimed bassist and educator Ian Allison, this pedal is designed to bring expressive, synth-driven textures to the forefront of modern bass playing.
Built from the ground up with working bassists in mind, the MXR Bass Synth Pedal delivers vintage analog warmth, contemporary digital control, and intuitive usability—all in a compact and road-ready housing. With a unique blend of classic synth waveforms, dynamic filter sweeps, and assignable modulation, this pedal empowers players to sculpt everything from sub-heavy synth-bass grooves to sparkling octave textures.
“It’s the pedal I always wanted on my board,” says Ian Allison, known for his energetic stage presence and genre-defying tone. “We designed this with real players in mind—something that sounds massive but doesn’t take a degree in synthesis to use. It’s about inspiration, not complication.”

This pedal marks MXR’s most ambitious foray into synth territory yet and solidifies Ian Allison’s growing role as an innovator in the bass community. Whether you’re laying down grooves in a pop production, experimenting with lo-fi soundscapes, or just want to unleash some sci-fi fury at your next gig, the MXR Bass Synth Pedal delivers the goods with power, tone, and musicality.
