In the words of ThorpyFX:

This fully Analog Chorus/Vibrato was designed from the ground up to provide the most incredible 3 dimensional chorus sounds with a level of versatility to meet the needs of all guitarists. Faced with hundreds of digital choruses on the market, Thorpy and Dan Coggins (Former Lovetone Pedal designer) decided to go fully analog and deliver that vintage chorus that can only come from an analog circuit. The Deep Oggin is voiced to provide a variety of chorus styles from deep and wet through to more subtle and shimmery sounds.
