NU-X Monterey Vibe, born to recreate the grand, yet complex, psychedelic rock guitar sound of the 1960's and 70's. It features all of the classic Uni-vibe style selections: Chorus, Rotary-Speaker, and Phaser pedal. We modernized the original 4 stage phaser circuit ( a pulsating bulb surrounded by 4 photo-resistors ) by replacing it with a powerful 32Bit floating DSP to process our custom algorithm. What was the outcome? A perfect mimic of the complex physical-phenomena of its original analog circuitry. NU-X Monterey Vibe generates a truly unique effect tone; a mix of chorus, tremolo, rotary, and phaser. This unique tone can be found in Pink Floyd’s ‘Breathe’, Robin Trower’s ‘Bridge of Sighs’, and the haunting audio mood created for ‘Machine Gun’ by Jimi Hendrix. The earliest Uni-Vibe effect pedal came out in the 1960‘s. Cutting-edge guitarists were seeking a replacement for the heavy rotary speaker amplifier--configured from a standard amplifier for the electronic pipe organ. The original Leslie speakers did have a charm of their own, but it was more than compensated for by gaining the phaser effect, and the ease-of-use of a simple pedal configuration. Just like the traditional Uni-Vibe pedal, you can switch between Chorus ( the Uni-vibe effect ) or Vibrato, by simply holding the foot-switch. In Chorus mode, the mix of Phaser and dry guitar signals produces a classic Rotary sound. In Vibrato mode, your pitch modulates between high and low. Both modes yield a rich, vintage vibe at any speed, intensity, or volume.
