Get to know them!

Whether your idea of synth-infused electric bass guitar is rooted in funky ’70s grooves, pounding industrial riffage, or stargazing pop sensibilities, the Bass Synth pedal from MXR delivers all that and more. Created in collaboration with professional studio/touring bassist, YouTube contributor, and all-around champion of everything low end Ian Martin Allison, the MXR Bass Synth provides a full palette of user-friendly controls designed to help you dial in the frequencies, responses, voices, and tones to shape your bass sound. Eager to plug in and get down? We hear you! The Bass Synth comes stocked with eight classic presets — inspired by a range of sounds, from Michael Jackson to Nine Inch Nails — so you can waste no time turning out your favorite riffs or creating indelible lines of your own. Unlock a new dimension of heart-pounding pulses, molasses-like movements, and silky-smooth stylings with the MXR Bass Synth pedal.

A multidimensional deep dive

Bassists at Sweetwater find the user-friendly control set as accessible to players with synth experience as it is to those taking their first plunge. Though the sounds the Bass Synth molds may be complex, creating them is fairly straightforward. Use the Shape button to establish the foundational waveform, then adjust the Mod and Envelope knobs to set the amount of modulation present in the sound and the filter response, respectively. Further tweak your tone with help from the Mix, Cutoff, and Resonance controls, where you can blend the dry and wet signals, manage the cutoff frequency, and inject your tone with an extra boost. The MXR Bass Synth is capable of bass sounds that are out of this world, no doubt, but it also provides hours of joyful and surprising sonic experimentation.

MXR Bass Synth Features:

  • Transforms your electric bass guitar into a salacious synth machine
  • Designed with champion of the bass guitar Ian Martin Allison
  • 6 control knobs — Mix, Sub Mix, Cutoff, Resonance, Envelope, and Mod — help you dial in the exact synth tone you’re after
  • Achieve more complex tones with additional harmonically tuned oscillators by using the Voice button
  • Select between 3 foundational waveforms — triangle, sawtooth, or square — with the Shape button
  • Choose between 8 onboard presets for inspired synth bass sounds
  • Advanced features include tap/expression control and stereo output mode
