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:
This forum's kinda slow, huh?
Did you run out of vintage pedals to reverse,clone etc?
I scored this off eBay a few months ago. The previous owner said he bought it in 1966, which I thought was rather early, so I opened it up yesterday to see if the date codes on the pots disputed that. It seems to be an interesting part of the UK fuzz box story. Cosmetically it obviously harks back to the FZ-1. I haven't got one of those pedals to compare but the scale and size is probably spot on the same....
There is a story and a lesson here. I found this through links on the fantastic wikipedia page about the brand. Still, I had to retrieve the pdf from the internet archive - I was under the impression that they don't usually store pdf files. There recently was another coffee table book on stompboxes, and I weigh my words. I haven't see Mike's book either. I doubt very much that any of them take the scientific approach: it allows us to...
I found no thread on the Colorsound Wow Swell, in the video below just referred to as Colorsound Wah. Nor is there a thread on the Solasound Wow Swell, which is, if I'm not mistaken, an earlier, internally different circuit with some deviations in the circuit.
Luckily AG traced the circuit, but from a pink unit?
picked this schem up over at the D*A*M forum. the fuzz is kind of interesting. kinda muffish, kinda not. i haven't seen this particular NFB diode configuration before- it might be fun to try.
hey guys, i just bought this on ebay for 20 bux...
anyone know anything about it? i know the board has been replaced, gonna hopefully find a schematic so i can make an appropriate clone of the original circuit.
found it on discofreq's website, with a great gut shot.
any info anyone can help me with is appreciated!!
here's the shot inside the one i bought...absolutely not the same circuit, and looks almost like a commercial board.
Traced this Kay Effector PCB layout from Google. Sorry it's a bit cramped.
I believe the op-amp is an MC1458, there is an unknown transistor in the LFO section that the PCB layout labels K9. I assume it's a PNP BJT just I can't say for certain. The speed pot is an unknown value though I assume it's similar to the one found in a Vox repeat percussion. Volume and tone values are also unknown, as well as the placement of the tone pot in the circuit though I assume it's on the volume pot input....
In the 70's, everybody and their mother seemed to be selling fuzz kits... especially if you you had surplus components lying around. So this unit was a kit, even though the packaging seems commercial.

This company was mainly building synth modules, but also sold some effect kits, among which this Fuzzorama.
Dewtron was the the trademark of the company run solely by Brian Bailey: Design Engineering Wokingham . Brian moved to...
Has anybody got any pictures of the ADA Ampulator circuit boards? I have got the schematics but these do not include a pcb layout. Pcb layouts were included in the documents for the Microcab which I built several years ago and these were really helpful when I did my one channel version. amnwsgwnfzrxec0ke5dw.jpg
I could have bumped an older topic but prefer a new one.
The concubine has been discussed but it does not seem that people have hands on experience playing the thing. Not so strange since it needs to be connected to an HH amplifier (which I don't have) in order to be powered and get signal.
I've reversed one but expect more errors to show up. The design topology is everything but conventional, as an example.
However, here's the job so far. It's a flanger and uses a SAD1024. Other than that...
