The J. Rockett Audio Designs Tranquilizer is a phase / vibe pedal from the company's Tour Series of pedals, designed to give you a plethora of phaser, univibe and rotary speaker sounds. Starting on the classic "45" phaser pedal platform, beloved for its wholly musical sound, JRAD gave the Tranquilizer some extra features to make it more versatile. A wet/dry control lets you blend in your desired amount of the effect, while the unique "Focus" knob gives you exacting control over the low-end "whomp" that wasn't adjustable on the vintage pedals.
