Gehirn Enterprises DeepVibe Modulation Optical Vibrato (Made in Australia)

Deep Vibe is a modulation pedal that is an optical vibrato, based on univibe style quad photocells, but many sounds can be achieved with it including, phaser, tremolo, vibrato, modulated filter, rotary tones and deep throbbing sub bass.

I haven't written one of my typical blurbs describing how crazy it sounds with a bunch of descriptive imagery and metphores yet, so you will have to make do with the YouTube Video I did for it. My partner Sinders says it sounds like "Mermaid Gunslingers from Hell". Skip to near the end if you want to hear everything cranked up and the modulation at it's greatest.
