Mojo Vibe Manual in pdf format (including addendum)

Addendum to the Mojo Vibe manual pertaining to the speed pedal jack in pdf format.

Mojo Vibe

Praised by pros and semi pros alike for it’s authentic "Vintage Uni-Vibe" sound, the Ultra Vibe has been known as "the one to own". And now the Mojo Vibe picks up where the Ultra Vibe left off. At half the size ( approx. 4 1/2" X  4") and weight of the original Ultra Vibe the Mojo Vibe will leave you with more real-estate on your pedalboard than any other true vibe effect available.

The Mojo Vibe is not a bells and whistles type of effect. The features have been chosen from customer suggestions and usability from my own experience as a professional player for over 35 years. So if you want simply the best vintage Uni-Vibe sounding pedal available, then look no further than the Mojo Vibe.


9 volt DC powered

Now you can use those nice power supplies that are available (like the Voodoo Labs Pedal power2) or an optional wall wart. That 9 volts DC is converted to 18 volts DC internally to retain headroom and ability to use the original bulb that is so very important in getting the right "throb" or "wobble" in the sweep. The mojovibe will not run on batteries and the US 120V wall wart is optional for $15.

Internally switched FET buffer pre-amp

Switched with a miniature DIP switch, you can choose the warm vintage input configuration or a modern fet buffered input for a brighter sound. This differs in that most vibe makers switch a simple resistor in and out for the two different styles, but it still chokes off the response of your guitar. With the fet buffer this will not happen. The only time the buffer (when selected) is present is when the effect is engaged. Not to be confused with a buffered bypass. It is still true bypass.

Speed Controller Input

Just about any passive type volume pedal or expression pedal will work with the Mojo Vibe. We sell the Roland EV-5 which is great as a controller. Of course some better than others, due to the value of the pot in the pedal. The ideal value would be a 100K reverse log taper. But I have found that many other values will work satisfactorily. To conserve space the Mojo Vibe uses a " stereo tip, ring, sleeve switching jack for the controller input. You can use it as is with expression pedals where the cord is already connected to the pedal such as Roland, Ensoniq and other keyboard expression pedals. To use a passive volume pedal you will need a special cord that consists of a " stereo plug on one end and splits into two mono " plugs. These are the same cables used in the channel inserts on mixing consoles and are readily available at most music stores.

Chorus / Vibrato Switch

Ok, so it’s not really a chorus as we know them, but we’ll stay with the original terminology. This uses a short bat (so it’s hard to break off) miniature toggle switch to decide the output. Either the original "chorus" / Uni-Vibe sound or a wild vibrato can be chosen with this switch.

Volume Control

Adjust the output to match the input level.

Intensity Control

Adjust the depth or "intensity" of the effect, also effects the bias of the sweep to some degree.

Speed Control

Adjusts the speed of the sweep. From a slow rolling phase to a bubbling, watery, pulsing throb.

True Bypass with LED that pulses in time with the speed setting. 

Aluminum Case

Chosen over steel for superior shielding properties and lighter weight.

And it's Purple!!!

The price is still $289.00 US.

Some of us already have box full of un-needed wall warts (well ok, most of us) or use one of many pedal board power supplies that are available. So, in an effort to save you and I both money. I'm going to offer our generic properly regulated 9 volt DC center negative 200 ma. power adapter. as a seperate item for $15.00 FOR US AND CANADA VOLTAGES ONLY

Sound Clips

Here are sound clips of the new Mojo Vibe from the Sweet Sound website. This clip was done with a 62 reissue limited edition Fender Stratocaster fitted with factory installed Texas Special pickups into the Mojo Vibe and then into a Nobels OD1-R. A black face Fender combo with 1x12" EV speaker was used for amplification. A Shure SM-57 about 6" away from the speaker into a Mackie mixer (for mic pre-amp only) directly into a Gina sound card into Cakewalk Sonar was used for recording. No eq was added.

Mojo Demo 1


Right now this is just a longer version of the demo that was on the old web site.
This was recorded about 5 years ago on a six track cassette recorder. The equipment used was a Black Face Fender Bassman head in a 1x12' combo cabinet, with an extra gain stage, a fuzz, and the Ultra Vibe. The guitar was a Fender American standard w/ EMG SA pickups. Bass and drum tracks are midi drums and bass.

MoFaux Vibe

The MoFaux Vibe is designed for the musician that wants the basic Original Uni-Vibe sound in an economical and small package. While not a "true" original Uni-Vibe circuit it does get surprisingly close and is not meant to be a full blown Vibe such as the Mojo Vibe. Here are a few clips I did of the prototype MoFaux vibe

MoFaux Slow --- MoFaux Medium

MoFaux : Cry Baby > MoFaux > Habenero Boost > overdrive > Fender Amp


9 volt DC adapter or 9 volt battery operation Hand matched FET transistors to insure full spectrum sweep Very small foot print
Price $150


The Swirly mojovibes came out well so we will try to get them in stock and the normal ones too.

The Mojovibe pedals are often backordered so there may be a delay in getting one to you. So please email for availability if you need it soon, and I will let you know if I have some in stock or how long it might be to get one to you.

Please use our new website for ordering. Best to use a credit card, not paypal, then we don't bill you till we ship.
