KMA Machines Geminus Stereo True Double Tracker FX Pedal

The KMA Machines Geminus is a compact powerhouse built around KMA’s proprietary True Double Tracker (TDT) technology, a system designed to authentically recreate the sound and feel of playing the same part twice. Not a chorus. Not a slapback. Not a synthetic doubler. Geminus delivers true double tracked realism in pedal form.

First introduced in KMA’s ENDGAME, the TDT algorithm was developed to behave like a real studio double track: subtle timing differences, pitch variation, and level interaction that feel human rather than processed. With Geminus, that same AI-driven technology is distilled into a pedalboard friendly format, making it easy to add fatness, depth, and stereo width to both live rigs and recording setups.

Controls for Time, Pitch, and Level allow you to fine tune how the doubled signal behaves, while the Width knob lets you spread the effect across the stereo field or keep things tight and focused. Whether you’re thickening single-note riffs, widening clean arpeggios, or adding authority to distorted parts, Geminus makes your guitar sound bigger without smearing your tone.

Flexible mono or stereo operation via TRS jacks means Geminus fits seamlessly into almost any setup, from simple pedalboards to complex stereo rigs. Premium analog electronics, 32-bit internal processing, and relay based soft switching ensure pristine audio quality and silent operation, whether used on stage or in the studio.

For tone hunters chasing size, space, and realism, Geminus delivers the unmistakable sound of true doubling, without ever feeling artificial.
