I received this pedal recently, it was found in a garage. It's in a rather sad state, as you can see from the pictures.
It looks like the Fuzz PCB is missing but I guess I can make the Wah work on its own.
I decided to take it apart, clean it and re-wire it. Below are a few shots of the PCB.
I've labelled the connection points on the PCB and am asking for help which ones are for the IN/OUT, 9V and POT. I'm sure this will be easy for the experienced builders.
essentially a superfuzz abnd univibe in one (big) box... love the damn thing to bits but its just too cumbersome to take on the road. i have never found a schem so am wondering a) does anyone have a schem b) could it be made into a smaller format and c) has anyone else based a stompbox on it?
Does anyone happen to know what part of the circuit effects the gating? I have been experimenting for weeks and getting a wide range of results, but I can't seem to figure out what components are the ones effecting the amount of gating. I know it can be done because there are mki pedals with a gate control. Just when I think I've pegged it, its wrong and doesn't work. I can usually figure these things out, but this is getting frustrating. Any help would be appreciated.

A self-proclaimed All-Knowing Guru is offering a corrected schematic of the Vox Repeat Percussion here:
There is at least one thing what the self-proclaimed All-Knowing Guru doesn´t know:
His schematic neither original nor is it correct - so it is more a fake.
For comparision purposes here is the (wrong) original schematic
and as FSB birthday present No. 2 is here a traced (and for this reason really correct) and tested schematic:
People like guts? ok, here are some others from our japanese hackerfriends (click on the pictures for high resolution):

I have the tranny numbers written down at home

It seems that some people have had trouble building from the schematic. If one of you guys has component side board photos it would go a long way toward confirming the schematics accuracy.
I did little of detective work for old VOX Tone Bender, and poor man variant also knows as a Jen Fuzz (or/and JEN Tone Bender)
Anyway, I have the poor man version and I did exact dimensioned replica layout, as well as the notes about most common variants.
My documentation contains six slightly different versions with minor changes from those goodshots I had stored on my hard drive (including rare silicon version). There can be versions some ware other unknown to me, if you know...
Today the Schaller Universal-Fußpedal is mostly referred to as Double Pedal . I have no idea how Schaller marketed this monster of a pedal internationally, but they surely had to find a more suitable name than Universal-Fußpedal - and a merely descriptive name would have been too long: a Fuzz/Treble-Bass-Booster/Tremolo/Swell-pedal with with dual treadle control. So as a consequence someone probably came up with Double Pedal .
I'm not looking for the truth about fuzz, I just enjoy googling the web more than crosswords.
'Satisfaction' by the Rolling Stones was released in early June of 1965 in the US, and only in August in the UK. Agreed, after the summer, fuzz is everywhere: in November 1965 McCartney puts fuzz on Think for Yourself...
But the Yardbirds' 'Heartful of Soul' is recorded on April 20th 1965 ... and Beck is using a Fuzzbox on that record. That's three weeks before the Stones record Statisfaction on May...
The Sabbadius Funky-Vibe sounds great (on the youtube vibeos I found, I recommend this one: ).
I have an pretty early Fulltone Deja Vibe, which is lacking this magic. As far as I know, it is, with regard to the circuit, an exact copy. But the components are different.
Could the magic of the Funky-Vibe be brought into the Deja Vibe with these other components, i.e. Matsushita 2sC828 and 2sC539 transistors? What about the photo cells? Sabbadius does sell the custom made photo cells.
Of all the tonebenders, I really do like the MkII version - It nails the Hendrix Voodoo Child sound when you put a well tuned wah pedal in front of it too.
I don't think Hendrix ever used a Fuzz Face - If he did, I don't think he liked it from what I have heard from folks supposedly in the know - forget the other benders - build a MkII - you won't be sorry you did.

Does anyone have a schematic for this thing? Or could someone verify a layout? I have a layout done by MoreCowbell a while back that's a trace of an original unit. But I wanted to do one that would fit in a 1590b.
After giving the exact clone layout a closer look, I noticed it has a lot in common with the DOD 250/Distortion + circuit. So I hacked apart a couple of Markm's layouts, and came up with something that looks like *should* work. I can't find a schem for it though.
Edit:
It still is identical to these units, check the corrected schematic by Lucifers Trip here
LRE Fuzz
Acetone FM-1 Fuzzmaster
Olson - X87 Fuzzmaster with factory schematic matching LT's corrections of the LRE
I spilled this one on HC already since it's I project I won't continue.
Here's my full schamatic and PCB layout file for a clone of the Shin Ei FY6, which has been around in many varieties among which the famous Shaftesbury Duo Fuzz.
Project is verified although I used 2SC1815's.
Use is, share it, and, abuse it if you want to. If you can and wanna make money on it. Go ahead! :wink:
