The Vintage Phase JF-06 pedal beautifully re-creates the classic phaser sounds of the 70's; that wide spacy, eerie phase effect that fans of Van Halen love! Easy to use, with just the single "speed" control knob--you can dial up that in-and-out of phase tone in no time! True bypass design minimizes tone loss. Aluminum alloy casing with stoving varnish finish.
