The DOD FX22 Vibrothang was designed to incorporate vibrato and rotary effects into one pedal. The Vibrothang functions more like a tremolo because there is no pitch alteration, but it also adds a phasing element that gives it a more wobbly character. With a few changes to the controls, the FX22 vacillates from a large, roomy swish to a tight, intense buzz.
This 2000s FX22 Vibrothang Vibrato is the second generation of the pedal, so it has the cleaner artwork and updated controls. "Speed" controls the rate of the vibrato, and "depth" controls the intensity. "Doppler" controls the amount of phasing, and "Image" sets the regeneration of the phasing. While the Vibrothang produces nice subtle sounds at lower settings, our favorite tons are found when you push Doppler and Image to the higher settings—this creates more intense and the most prominent wobbly sounds.
This 2000s FX22 Vibrothang shows some minor cosmetic scuffs and signs of use, but it's fairly clean all around. The battery compartment is still in tact, and that's often a problem with this style DOD enclosure. No issues with the switch, either; it functions 100% as it should. This pedal produces cool sounds that are different from what you find from more common vibrato circuits, especially you crank up "Doppler" and "Image."
