Steve Stevens:"We actually did an AB test with your Vibe
and for Les Paul style guitars, we found it to be much more
useful. I love the pedal"

The VibeTool®, a compact and flexible Vibe based on the Shin-Ei Uni-vibe 

The VibeTool is based on the original Shin-Ei Uni-vibe extended with features that increase useability. With the TMF adjustment you can dial in the amount of bottom to adapt to different types of guitar.

Like the original Uni-vibe, the VibeTool is a 4 stage phase shifter device implemented with discrete transistors and 4 phase shifting stages based on variable RC filters build up of a capacitor and a Light Dependent Resistor (LDR). The value of the resistance is varied by means of a light bulb with a sinusoidal control signal thereby creating the phasing effect.

Shin-Ei Uni-vibe History

The Uni-vibe was developed by the company Shin-Ei in 1968 by engineer Fumio Mieda. It was meant to be a Lesley simulator but sounds more like a phase shifter device as it is based on phase shifting  technology. The Uni-vibe was one of the first phasers available in the market. The major difference with a standard phaser (e.g. MXR Phase 90) is that the four phase shifting stages each having a different frequency setting making the “wobble” sound more musical.
Notable users of the Uni-vibe are Jimi Hendrix, Robin Trower and David Gilmour of Pink Floyd. The real Uni-vibe sound can be heard on Robin Trower’s “Bridge of Sighs”, Jimi Hendrix’s “Machine Gun” and Pink Floyd’s “Breathe”
