The UV-1, Dunlop’s faithful recreation of this legendary psychedelic effect, delivers that swirling, spacey “Bridge of Sighs” tone, plus a lot more. The Chorus mode sounds thick, phasey, and much like a rotating speaker. The Vibrato mode modulates the pitch of the played note, delivering a cool, quivering texture to your sound. The UV-1 sports hand-matched photoresistors, a long-life incandescent lamp, and custom lamp housing to protect sonic integrity. Power: Dunlop ECB004 18 volt AC Adapter.
