4 stage OTA-based phaser with a three way toggle switch to select between the ranges of modulation: Rate 1 is slow sweep mode, Rate 2 kills the LFO and allows you to use the Grand Orbiter as a fixed resonant filter and Rate 3 is fast sweep mode. The Depth control blends the shifted signal in with the dry signal and controls the intensity of the effect. The Sweep control governs the peak frequency of the phased signal's tone, turned full clockwise the sweep is lively and intense, whereas turning counter clockwise yields a darker, more laid back peak. The Resonance provides a wide range of control over regeneration and at higher settings adds a more pronounced and resonant tone. You can also use the Grand Orbiter as a true pitch vibrato with the "Phase/Vibrato" switch. When in "Vibrato" mode, the dry signal is removed and the Depth controls acts as a volume control.
The new version 3 released in November 2017 features the new Flexi Switch switching which allows to select between momentary or latching operation, as well as a soft-touch relay-based switching for truly silent and effortless operation with increased long-term durability.
