KMA Machines Geminus: Automatic Double Tracker For Epic Stereo Effects!
AI-driven stereo widener inspired by Endgame!
Endgame by KMA Machines was a huge success for the Berlin-based company thanks to its clever combination of stereo cab loader, double tracker, and signal flow. With the KMA Machines Geminus, the double tracker from Endgame has now been freed into its own pedal for epic stereo widening effects.
KMA Machines Geminus Doubles Your Signal Better Than You Can
Doubling guitars is pretty much a standard practice in modern da rock and metal music production. The idea is to record a riff or solo twice, as similarly as possible. Then you hard-pan the two recordings in your DAW, one on the far left and one on the far right.

Thanks to the minimal variations, it’s still one riff playing, but it sounds super wide and fat. But what if there is only one guitar in the band? Or the second one is busy playing solos? With an effect like the KMA Machines Geminus, you can solve this problem.
Some may wonder whether a similar effect could be achieved with a chorus, a short delay, or an ensemble effect. Not with the same quality. With the effects mentioned, the doubled signal quickly becomes blurred, leaving little of the desired width.
Epic Stereo Width With Geminus
In recent years, stereo signal flow has become increasingly popular on pedalboards. A pedal like the KMA Machines Geminus is therefore a fitting addition. On it, you can choose between three modes for the signal flow: mono to mono, mono to stereo (default setting), and stereo to stereo.
This means that the Geminus works just as well in pure mono setups as it does at the point where the signal transitions to stereo, or even in pure stereo boards. You control the intensity of the double-tracking effect with the large Width knob. Turning it to the left keeps the signal completely in mono. The more you turn the Width knob to the right, the more the original and double-tracked signals are split between the left and right channels of the stereo panorama.

According to KMA, the doubling is generated through AI-powered technology in the pedal, which produces a very realistic-sounding copy for any type of input, whether clean, crunch, distorted, or even synthesizer. Until now, this technology was only available in Endgame. With Geminus, KMA has successfully ported the technology into a smaller and more affordable pedal.
TRS, Pitch Modulation, And More
However, the KMA Machines Geminus offers even more. There are three additional settings that allow you to modify the double-tracked signal to suit your preferences. The time control determines how much the doubled signal is delayed from the original.

Level controls the volume of the doubled signal, with the knob its maximum on the right being the same volume as the original. In addition, the three-way Pitch switch activates subtle (up) or less subtle (down) pitch modulation of the doubled signal for a slight chorus effect.
The input and output jacks are located on the top panel, which is great for tight pedalboards. Both jacks are TRS format, so you can use a TRS cable to send stereo signals into and out of the pedal. In addition, the Geminus can be switched between buffered bypass and true bypass as needed.
