Cosmodio Launches the Gravity Well

Cosmodio Launches the Gravity Well

The second release from Cosmodio is a first-of-its-kind modulation effect that features an Expression Pedal/Tap Tempo input for dynamically controlling the LFO’s speed or depth mid-performance.


The Gravity Well is a dual-sided pedal featuring a tremolo on one side and a wavefolder on the other. When both circuits are active a third effect emerges – a refractor – a first-of-its-kind modulation effect produced by integrating the tremolo and wavefolder to rhythmically and fluidly warp and unwarp your signal, producing a dazzling variety of never-before-heard sounds and textures.

The pedal’s five-knob control set includes wavefolder Volume; wavefolder Gain (for controlling the amount of signal folding); modulation Speed and Depth; and a Waveform control to select between 8 LFO shapes that include classic shapes as well as randomized movements.

The Gravity Well’s capabilities are expanded by three toggle switches:

  • “Flow” determines the signal flow when both sides are active. Tremolo into wavefolder or wavefolder into tremolo, dramatically changing the effects’ interactions and the sonic result.
  • “Voice” selects between three different output voices of the wavefolder: full wavefolding, focused wavefolding, or a wavefolder and clean signal mix.
  • “Tone” allows you to select a bright, dark, or balanced output tone of the wavefolder.

The Gravity Well encompasses familiar and exotic sonic territory, creating a pedal that’s both thrilling and approachable. Its carefully spaced control layout is optimized for easy spontaneous adjustments. Its top-mounted input, output, and power jacks ensure an efficient footprint on a pedalboard or desktop. It features faceplate artwork by accomplished pop-artist GOLDSUIT.

Gravity Well features include:

  • Selectable true bypass or buffered bypass switching
  • 9-volt operation via external power supply - no battery compartment
  • Built in US
  • Internal DIP switch controls for customizing expression pedal function, tremolo volume, and tone switch range.

The Gravity Well carries a $279 street price. It is available for pre-order at the https://www.cosmod.io/ website. It will fully launch and start shipping on November 19.

Know what a wavefolder does to your guitar signal? If you don’t, that’s okay. I didn’t either until I started messing around with the all-analog Cosmodio Instruments Gravity Well. It’s a dual-effect pedal with a tremolo and wavefolder, the latter more widely used in synthesis that , at a certain threshold, shifts or inverts the direction the wave is traveling—in essence, folding it upon itself. Used together here, they make up what Cosmodio calls a sonic refractor.

Does the type of finish on an electric guitar—whether nitro, poly, or oil and wax—really affect its tone?

There’s an allure to the sound and feel of a great electric guitar. Many of us believe those instruments have something special that speaks not just to the ear but to the soul, where every note, every nuance feels personal. As much as we obsess over the pickups, wood, and hardware, there’s a subtler, more controversial character at play: the role of the finish. It’s the shimmering outer skin of the guitar, which some think exists solely for protection and aesthetics, and others insist has a role influencing the voice of the instrument. Builders pontificate about how their choice of finishing material may enhance tone by allowing the guitar to “breathe,” or resonate unfettered. They throw around terms like plasticizers, solids percentages, and “thin skin” to lend support to their claims. Are these people tripping? Say what you will, but I believe there is another truth behind the smoke.
