The Earthquaker Devices Grand Orbiter Phase Machine V3 is exactly that: a phase machine. This 4-stage, OTA-based filter can do it all. Stationary and resonant, slow and mellow, fast and swirly- whatever you want, just switch the Rate toggle, dial it in and the Phase Machine delivers. Also, switch it over to Vibrato and it acts as a full-on vibrato pedal with the dry signal removed and the Depth control acting as Volume. Four stages. Infinite possibilities. One grand machine.
