The wait is over, the ULTRA VIBE II is back. From the mind of Bob Sweet to your pedal board. This beautiful sounding handcrafted pedal can be yours.




I tested a bunch of univibe clones with Jim Weider and this was the one... he grabbed one and Jesse Gress from Todd Rundgren's  band, and Guitar Player magazine, heard his and Jesse grabbed one too.

Usually in stock, ask to confirm.

These have an AC cord for USA style 120V AC, if you want to use it in other countries you will need a voltage converter.

Chorus/Vibrato Switch - Selects between the classic Uni-Vibe chorus sound or vibrato.

Volume Control - Used to either match the effect output with the unaffected bypassed signal. Or to ad a slight boost to the affected signal.

Intensity Control - Controls the depth or the amount of the chorus or vibrato effect.

LED Indicator - When the effect is engaged the Led will light and also pulse to the speed set by the speed control (#10). When off the effect is bypassed

Speed Control - This controls the speed of the sweep in the Ultra Vibe. From slow rolling phase to watery bubbling "Leslie" type sound. The large oversized knob is used in an attempt to make it easier for those who do not wish to use the option of a pedal controller, to adjust it with their foot. This knob when a control pedal is used, so you have control over the total speed range is totally bypassed

The hole on the bottom of the Ultra Vibe is the access hole for the trim pot that controls the depth and center frequency. It can be looked at as a bias control and works in conjunction with the front panel intensity control. Adjust to your taste just be careful not to force the trim pot as it is delicate. What I do is set the intensity on full and then adjust the trim pot to the extreme of what I would use and then from then on use the front panel intensity control.

Expression control jack: This jack is for controlling the speed with an external expression pedal, instead of the built-in speed knob. A standard expression pedal like the Boss EV5 will work fine on the ULTRA-VIBE-II, unlike the original ultravibe which required a special univibe dual pot controller like the original (not Dunlop) Uni-Vibe pedals.
