Infinitely Organic.

Some might say we’re driven. When our engineers lock themselves in our sound design labs for months on end, you might say we’re obsessed. We have been dedicating ourselves to forging a collection of the most organic, luscious, expressive, and versatile modulation effects ever heard.

It was an enormous mission—we painstakingly studied the nuances of the legendary modulations of celebrated tremolo effects, phaser pedals, chorus units, and more from the last five decades. We didn’t stop at faithfully capturing these warm and lush vintage sounds—we expanded their vocabulary with extended versatility and sonic possibilities never before heard.

Mobius Modulation Multi-Effect Pedal

Open Up the History Books of Music.

Mobius gives you twelve legendary, versatile, and inspirational modulation machines, all in an easy-to-use package. Go from mouthwatering vintage chorus sounds all the way to syrupy psychedelic phasers. Get classic, pulsating tremolos all the way to warbling crushed bits. Mobius opens up the history books of music and provides new sounds and inspiration for all of your musical ideas.

We knew we must surpass what has been done—in sound design, audio quality, hardware design, and processing power. Utilizing an insanely powerful SHARC DSP, every drop of power is harnessed. Top it all off with 200 presets, full MIDI implementation and a unique Pre/Post Mode and you’re on your way to modulation ecstasy.

  • The quality of the Mobius is superb. It’s dead silent—quiet enough to use for outboard mix buss duties.
    Charles Saufley
    Premier Guitar
  • This isn't just for guitars, though, as the Mobius can handle up to +8dBu input levels, which means that all manner of signals played live or sent from a DAW are ripe for treatment.
    Ingmar Kiang
    Sound on Sound
  • Mobius could conceivably replace a raft of pedals in a guitarist's live rig, adding programmability and its clever pre/post functionality, while recordists will its appreciate its superb sound quality, flexible handling of input levels and sheer range of effects. As a programmable modulation pedal suitable for a variety of instruments both on stage and in the studio, the Mobius ranks among the best of its type.
