Dawner Prince VIBERATOR Stereo Vibe Guitar Effect Pedal

Calculated at checkout

Viberator is the premium, stereo version of the vintage, Uni-Vibe® type phase shifter with a number of modern options. Utilizing all analog circuitry in a very compact design, Viberator impeccably delivers all those deep, natural and watery phase and shivering vibrato sounds.


Control adjusts the thickness and throb of the vibe (chorus) effect from subtle waving all the way to a deep and strong «heart-beat» like warble. In vibrato mode it adjusts the amount of pitch de-tuning effect. 

Control adjusts the rate of the pulsations of the vibe (chorus) or vibrato effect. Viberator has an extended speed range in comparison with the original Uni-Vibe and is customized to deliver balanced rotary tones even on maximum speed setting.

Control modifies the waveform that drives internal light bulb. From perfectly symmetrical sine wave in middle pot position to distorted waveforms in either end positions, this controls is unique and provides various sound effects from true vintage vibe to a new and interesting phaser sounds.

Chorus / Vibrato switch
Selects between classic Uni-Vibe chorus and de-tuning pitch bend vibrato mode.

Vintage / Modern switch & Bright trimmer
Vintage mode engages original Uni-Vibe input circuitry resulting in a warm and slightly darker tone, while Modern mode engages input FET buffer, resulting in a more brighter overral tone. The brightness in Modern mode can be further adjusted with Bright side trimmer. This control is very useful as it allows the pedal to be matched with any amplifier and /or guitar pickups.

Mono/Stereo outputs
Viberator is the most compact vibe pedal with true stereo outputs for real 3D, rotating speaker sound. When in Chorus mode, signal at stereo output is a 'mirror image' of the signal at mono output.

Volume controls
We have added separate volume controls on output channels for even more versatility. Output volume levels are slightly above unity gain with controls set fully clockwise.

Exp In
This input allows the speed of the effect to be controlled with an expression pedal. Viberator accepts any standard expression or volume pedals with 10K pot (e.g. Roland EV-5). Plugging in an expression pedal automatically disengages Viberator's Speed control potentiometer.

Gain & Offset
Gain and Offset control operation of the internal light bulb that illuminatates photocells and are used to set the right sweep and throb sound of the effect. Gain sets intensity range and Offset sets the balance of the sweep of the effect. These controls are factory preset.

True Bypass / Bi-colour LED indicator
Viberator utilizes True Bypass switching system on both mono and stereo channel. Status LED flashes in time with the speed setting and lights yellow when the effect is bypassed or blue when the effect is engaged.

Viberator accepts standard 9V DC on the input which is internally converted and regulated to 15V DC (Uni-Vibe operating voltage) to assure plenty of headroom and dead silent operation. Viberator also utilizes internal reverse power polarity protection circuitry.

Dawner Prince Effects: VIBERATOR™ - Stereo Vibe (09:52)
http://www.dawnerprince.com I've tried many great takes on the classic Univibe circuit over the last few years. I don't think any have been as refined as the DPE Viberator and I'm pretty sure that none have offered stereo output, internal controls for gain and offset, vintage and modern modes, separate volume controls for the stereo outputs, a LAZY mode, expression pedal control over the rate... The list goes on. And it sounds like sex. Zoran never lets us down. All of the Dawner Prince Pedals to date have been well above average. The Viberator is no exception. If old-school Univibe action with added and very welcome features is your thing, then look no further. One thing I forgot to mention in the video is the Bright trimpot which adjusts the Brightness in Modern Mode. Want more zing?
