KORG Nuvibe Vibrato Chorus Effector

Main Features

• Resurrected under the supervision of the developer of the original model! New features for today's musicians have been added
• Discrete design using 79 transistors. The CdS photoresistor that lies at the heart of the sound is simulated by an original circuit using transistors
• The WAVE sliders allow users to create their own LFO waveforms
• New buffer circuit designed by the developer of the original model, unlatch switch bypasses the internal circuitry when the effect is off
• Battery operation is also supported (six AA batteries allow up to four hours of operation)
• True bypass design that was not provided on the original model
• Dedicated expression pedal is included, allowing the modulation effect to be controlled

The Korg Nuvibe Vibrato Chorus Effector is a rebirth of the original legendary modulation effect unit from 1969 under supervision of the original developer.

Loved by guitarists for decades, it's a Japanese made modulation-type effect unit that made a blazing debut at the Woodstock festival - you already know the one we're talking about. The inimitable sound of this distinctive modulation effect has captivated numerous guitarists and audiences. Yet, because only a very small number of the original units exist, and because the circuit itself was not accurately understood and its components were difficult to obtain, it was rare to have the opportunity to try out the unit that produced these famous sounds. Such factors elevated the original to a semi-divine status. Numerous clone models were produced by major manufacturers and boutique shops alike, but all of these remain facsimiles that are pale imitations of the original model. Now, this legendary classic has been reborn under the ideal circumstances of the original engineer's supervision. Starting with original circuits that simulate hard-to-obtain parts, the distinctive modulation sound has been perfectly reproduced. Not content with a simple reproduction, new WAVE sliders have been added, allowing original waveforms to be generated. This highly sought after pedal with a long history of allure is now unveiled in its new incarnation: the Nuvibe.

It was during the 1960s when the original model first appeared. Its origin is so uncertain that even the people who were involved at that time are not sure of the circumstances through which this model went out into the world. What is clear is that in 1969, a legendary guitarist used it in a historic performance, drawing the attention of guitarists all around the world. Now for more than half a century, it has reigned as a great effect unit. This enigmatic classic in the history of effect devices has been reborn under the ideal conditions of the supervision of the original developer. As on the original model, it provides a switch for selecting either vibrato or chorus, and INTENSITY and SPEED knobs for producing that distinctive effect. The buffer circuit that has such an important impact on the sonic character has been also been newly redesigned by the original designer for the 21st century. And a great bonus: a dedicated expression pedal is also included.

The CdS photoresistor at the heart of the original model is a component that varies its resistance according to the strength of light, and it produces a distinctive effect by using the varying brightness of a small lamp to modify the output signal. Unfortunately, this component is now restricted as a hazardous substance, and cannot be used. Finding a substitute for this part was an absolute requirement in order to match the original model, and this was the single most difficult impediment to overcome. Success was finally achieved with an original design created under the supervision of the original engineer: a discrete circuit that uses an astounding 79 transistors to form the heart of the Nuvibe.
WAVE sliders for producing the LFO waveform allow the creation of original waveforms
The Nuvibe is not simply a facsimile of the original model. It provides ten WAVE sliders that allow users to create their own LFO waveforms. This lets you produce a wide variety of effects including sounds faithful to the original model as well as your very own custom sounds.

As on the original model, a dedicated expression pedal for controlling the modulation effect is included. Since this lets you use your foot to control the distinctive modulation, it's a great way to enhance your stage performances. There's also an unlatch switch that lets you cancel the modulation effect by returning the pedal to the heel-down position. Because we have meticulously recreated every detail, you can even take advantage of the unit's effect as a buffer amp just as on the original model.

The Nuvibe contains numerous design features that meet today's needs. Its two-way power supply allows operation on batteries as well as with an AC adapter. It also features a true bypass design as required by guitarists who care about their sound.
