KMA Audio Machines Horizon Pedal. This incredible pedal creates an immense array of JFET phaser sounds. By combining abundant analog JFET phasing with digitally controlled dynamics, Horizont creates a lively and expressive modulation experience, while providing experimental and creative features that will drive phasing well into the 21st century.

Set the SPURTCONTROL switch to LFO to allow the SPURT control to adjust the internal phase speed. On the other hand, by pushing the switch into ENV (Envelope) mode, it allows you to dynamically modulate the speed across the entire LFO speed range, depending on the intensity of the input source (for example, when it hits the chains hard). You can also combine the SPURT knob and the envelope by moving the lever to LFO+ENV, where SPURT adjusts the minimum speed. For greater control, you can even connect an external expression pedal/CV source (0-5V) to alter the minimum speed on the fly, or you can use the Tap Tempo switch (tap twice) to adjust the speed according to the tempo of your music.
