The DOD FX22 Vibrothang is a legendary vintage modulation pedal from 1995—a collector's favorite for its distinctive dual-circuit design. This red unit combines optical tremolo with a 4-stage phaser running off a single LFO, delivering everything from warm Fender-style swell to lush Uni-Vibe swirl. Four intuitive controls let you dial in your sound: RPMs adjusts modulation speed, Drop shapes low-end phase depth, Intensity controls the phase effect's sweep, and Image blends between tremolo and vibrato characters. Whether you're chasing vintage warmth or experimental texture, the Vibrothang's hybrid approach opens sonic territory most single-effect pedals can't touch. A true gem for players and collectors who appreciate unconventional gear with character. This pedal is in good condition.
