Vintage Uni-Vibe Repairs
Our Customers Worldwide


People all over the world have send us their precious old Uni-Vibes and we have successfully repaired all but one. Here are a few of our customers...



John E. - MI, USA

John's Uni-Vibe had the dreaded funky circuit board disease so common to old Uni-Vibe's, I installed one of my Auxillary LFO Modules, replaced his power supply cap's, and he's good-2-go.

MrNoName - NoTown, USA

MrNoName sent his Uni-vibe in to me for the four most common repairs, LFO rebuild, Bulb Driver rebuild, Power Supply Caps, and Bulb replacement.

He's too funny, said I could put his reference on my website "as long as you don't use my real name", well ok then MrNoName.

(BTW, it was MrNoName that dubbed me with the Dr Vibe moniker)


TJ sent his Uni-vibe in to me because his LFO stopped working, it works now!.

Mike S. - FL, USA

Mike's Uni-Vibe had the dreaded funky circuit board disease common to these old effects, his was un-repairable so I installed one of my Auxillary LFO Modules.

Tim K. - IL, USA

Tim sent me his early-production Uni-Vibe for repair, his vibe had the dreaded funky circuit board disease that plagues many of these vintage units. This was one of those tough-dog-job's because this particular Uni-Vibe had issues well beyond typical parts-replacement style service. Took a lot of work but I brought Tim's unit back to life and it sounds very good if I say so myself.

(from Tim's email)
"...thank you for everything...I was given the Uni-Vibe in 1988, several times over the years i tried to have it fixed. In the early 90`s a repairman had it for a while but told me he could`nt get it working. In fact it never worked the whole time i`ve owned it, today was the first time i have ever heard it function. I can`t put in words how thankful i am of your skill Brad thank you !! -Tim."

Phil V. - NY, USA

Phil sent his late-production Uni-Vibe in to me for repair, his vibe needed the LFO, lamp-driver, and power supply work.

Brad P. - TN, USA

Brad sent me his Uni-Vibe which needed some care and attention.

Mark S. - MN, USA

Marc sent me his 'ol Uni-Vibe for some service/tune-up work, the LFO was dead from funky circuit board disease, his vibe got a "graft" and is doing fine now.

Jay M. - NY, USA

Jay sent me his Uni-Vibe for some service/tune-up work, the LFO was getting really weak and turning the Intensity knob up full barely made it vibe.

Will C. - CA, USA

Will sent his Uni-Vibe in to me for some minor service/tune-up work, Will's Uni-Vibe is one of the few in near mint condition Uni-Vibe's I've had come across my workbench.

Eric T. - PA, USA

Eric sent his Uni-Vibe for some LFO work, his was another one of the few vibes in near mint condition.

Something very interesting here, be it a coincidence or whatever, Eric's vibe (pictured above) and Ricki's vibe (pictured below) were not only in my shop at the same time (June 2013) they were nearly identical and appeared they could have been built at the same time (day/production-run). Most Uni-Vibe's I've come across although they are all built "similarly" don't have the "exact" same parts and/or wiring (wire colors per connection) on their main boards, but these two did have exactly that. In fact the only difference between these two Uni-Vibes was the Vibrato/Chorus switch wiring was inverted, otherwise these two were identical in all aspects.

Ricki C. - CA, USA

Rick sent me his Uni-Vibe for some LFO service work, and a tune-up.

Jörgen R. - Stockholm, Sweden

Jörgen sent me his later model Uni-Vibe for some power supply and DIN jack work. A couple things of note were the power transformer did not have the unsual "02-1-05" marking printed on the top, it had a .005uF cap instead of the usual .0047uF, and had some 1uF caps in the LFO section of a brand (AL) I've not seen before in stock Uni-Vibe's.

Ronald D. - CA, USA

Ronald's Uni-Vibe needed some LFO work, power supply capacitors, and a tune-up.

Marc D. - Munich, Germany

Marc's Uni-Vibe came all the way from Munich for some work. His vibe was interesting in that the Shin-Ei stamp/logo was on the inside of the chassis rather than the bottom.

Marc also had a "Brand-F" pedal that needed repairs, apparently Mr.F wouldn't help him with it so I agreed to fix it for him since he was sending his Uni-Vibe to me anyway.

BTW, I don't work on brand "F" products.

Trey Anastasio (PHISH) - VT, USA

Brian Brown (Trey Anastasio's technician) sent me one of Trey's Uni-Vibe's which needed the usual work. This one appeared to be a "late" mfr unit.

A couple weeks later Brian sent me a white-logo and an ali-logo of Trey's Uni-Vibe's to have internal speed pots installed.

Here's my completely reversible mod where I add a speed pot to the front panel using a custom made mounting plate that fits exactly where the original DIN plug socket goes. This plate can be removed and the unit restored to it's past condition before this mod was made.

(no drilling!)

Ed D. - NJ, USA

Ed sent his Uni-Vibe which needed some luv.

"Celt" - PA, USA

"The Celt" sent his Uni-Vibe which needed some LFO work, power supply capacitors, and a tune-up.

B.G. - CT, USA

BG has a Heavens Vibe that needed a little work as it was humming badly. I don't normally service other makers vibe's I agreed to take a look at it for him.

Turned out it needed waaaay more than "a little work" so BG sent it back to it's maker in Japan.

Paul W. - CA, USA

Paul had a box of gear he sent me for service but his Uni-Vibe specifically was in really bad shape (didn't work at all) which was a bummer for him because said he might want to sell it. Someone had been inside it and amoung othe things replaced the original light cover with a home-made one.

Paul's vibe needed quite a bit of work to bring it back to life, new LFO bulb, complete Cap-job, power switch, DIN jack & plug, 1/4" input and output jacks, and replacement of the broken speed pot in foot controller.
(BTW, I also made him a new "vintage correct" light shield)

Unfortunately a couple months later I get an email from Paul with the complaint "you did not fix my vibe 100% as I asked" and explaining "it does not do "slow speed" as it should. Paul also communicated to me that he felt I embarassed him in front of his buddies and said "it's a bummer the unit was not fixed and tested before sending it back to me". I asked him to send it back to me and I went over all the previous work I had done, everything tested to spec but it indeed did not do the normally slowest speeds (my own speed foot controller worked just fine with his vibe) so focusing on his foot control pedal I noticed his rack-n-pinion gears on his speed pedal didn't look right (looked like Dunlop wah gears):

Sure enough, the rack-n-pinion gears in his foot controller were indeed not the "normal" ones used in Uni-Vibes, his had a different tooth count than normal vintage speed pedals (I suspect someone had replaced them with modern wah gears at some time) and since the gear ratio was not the same it did not allow full rotation of the speed pot and so the lowest speeds were not available. Paul's slow speed problem had absolutely nothing to do with my work, it was strictly a mechanical issue. Bummer for Paul is there are no NOS rack-n-pinion sets to be had (these days) so it's just not something I could fix for him, but more imortantly it's not something I did when I serviced his vibe the 1st time.


I communicated all this to Paul but he was convinced his problem was my fault. He requested I return his vibe and declined to provide me any compensation for my additional time working on his vibe. Paul has his vibe back now and unfortunately he is no longer one of our customers, but moving forward we wish Paul all the best.

The gist of all this is the fact that while I can do much to fix these old vibes, I may not be able to get some customers 100% fixed/restored as I don't have certain parts which are not available anymore.



Red Slim - NSW, AU

Red sent his vibe to me for service, it needed a refresh and some bit-n-bobs straightened up. Red's vibe is one of the few in particularly good shape, it's always nice to work on these when they're nearly spotless and well kept.



Jim B. - VA, USA

Jims vibe needed a bit of work, mostly the usual work and a good clean-up, but check out the power switch someone had replaced:

Got his vibe all fixed up and put a decent NOS type power switch in there. Looks good now!



Steve H. - GA, USA

Steve's vibe needed quite a bit of work, it needed restoration because sometime in it's life it was converted to use another speed pedal and put a new jack on the front panel and a stomp switch where the output jack was, and someone (with good intentions) tried to do some work on circuit board inside:


We got Steve all fixed up, and built him one of our speed control pedals to work with the original DIN jack on the front panel as it should be on a vintage unit.



Jeremy R. - IL, USA

Jeremy's vibe needed the usual work and a hole pludded in the front panel.

Jeremy's vibe sounds really good as vibe's go.



DeeDee J. - MO, USA

Dee Dee James is the guitar tech for Bootsy Collins, he sent me one of Bootsy's uni-vibes for some work.



Ed A. - PA, USA

Ed's vibe needed some fairly extensive service, several bad transistors were replaced, a full cap-job, as well as a new DIN jack.



Raymond B. - PA, USA

Raymond sent me his Uni-Vibe for some luv, his needed to be restored from someone's earlier "repair" work.

Then later, Raymond sent me this very cool cousin of the Uni-Vibe, it's called a Nomad Verberola which needed some work the mode switch replaced which is an extrememly hard to find part.



Jason H. - FL, USA

Jason sent me his newly aquired vibe for some service work.



Leif C. - OK, USA

Leif sent me his vibe for some normal service work.

Miguel S. - Spain

Miguel sent me his vibe for some work all the way from Spain, though it was working, it didn't sound like a vintage Uni-Vibe.

After inspecting the unit, it turns out someone had converted it to be LED driven instead of light bulb driven as seen below:

No worries, I quickly restored the unit to it's former glory and it sounds great now.






Rick G. - CA, USA

Rick sent me his vibe for a tune-up.






Alan H. - CH, USA

Alan sent me his Resley Tone for a re-build.






Albert R. - NY, USA

Albert sent me his Uni-Vibe for some TLC.






Brian M. - MN, USA

Brian sent me his Uni-Vibe for some TLC, and adding the internal speed control replacing the DIN jack.
(a completely removable/reversible mod)






Jack H. - CO, USA

Jack sent me his Uni-Vibe because the LFO was failing (wouldn't vibe), got him going again worries!.






Reid B. - IL, USA

Reid sent me his Uni-Vibe for some TLC.






Harley Fine - NYC, USA

While not a vintage Uni-Vibe this one needs an honorable mention, Harley Fine who runs a recording studio in New York sent me an unusual piece for some work which was a univibe built into an old Leslie foot controler. Even though I don't normally work on "other" vibes, I liked this cool piece built from an old Leslie pedal and agreed to take on the job replacing the RG circuit board.

I say cool because the Uni-Vibe was originally developed to be an electronic Leslie simulator!

(from Harley's email)
"Got the vibe this morning, what a nice difference in the sound, really engulfs the guitar in a nice way that the RG one only hinted at... sounds more liquid and sexy!!"

Harley whipped up a nice little youtube video when he got his unit back from my shop, IMHO it sounds very cool. Harley can be reached at:

This Old Vibe ...still works!

All references on this page to the name Uni-Vibe are specifically meaning the original effect pedal made in Japan by the Shin Ei company in the late 1960's to mid 1970's and not any other brand or maker of vibe pedals. Currently the trade name Uni-Vibe® is a registered trademark of Dunlop Manufacturing who does not manufacture vibes like the vintage Shin-Ei (Japan) uni-vibes pictured on this webpage, they make their own version which does not use Lamp & Photocells as the vintage (Shin-Ei / Japan) units did. Also for the purpose of clarity, there is an LLC registered in the USA state of Texas as "Shin Ei" claiming to be the original Shin Ei (of Japan) which it is not.
