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....
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...
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...
I friend of mine gave me a Morley SLDW for repair.
I found that the original schematic do not corresponds with the circuit,
it was therefore necessary to trace the circuit.
One more LED-LDR combination in real circuit and a somewhat different wiring identified.
The owner cannot rember if the pedal had been modified sometime in the past.
In the original schematic 7812 voltage regulator is shown, in the real circuit it is jumpered.
Likewise the power supply is 18 Volts DC in the schematic...
Not an evil japanese .... no.... the Amplifier Cooperation of America produced the Fuzz King . When you look inside, you see one 1,5V battery, 3 x Ge-transtistors 2 x 10k resistors, 2 x 100k resistors, 2 electrolytics.... seems to be a Maestro FZ-1A clone/derivate.....
I traced the circuit of my Jen Double Sound Super many years ago, had some help from Paul Marossy from the old DIYGuitarist site. The wah section is identical to the original Cry Baby, and the fuzz section seems to be a no knob Vox Distortion Booster. It sounds great.
