Super rare Colorsound Vocalizer in box. 9.5/10 condition with original box. Works 100% and sounds AMAZING. These are so painfully rare, and to find one in this condition and in the original box(been buying/collecting vintage and boutique pedals for over 16+ years and I've never seen...

Note that in the schematic above this is a PNP positive ground device. The original transistors were silicon devices, I think that I have sourced some from somewhere...
I bought this new in the late 70s. The board was removed in early 80s and installed from memory recently. I'm not able to find anyone who has this version. The board says EH 5200-1C NP. Does anyone have this version who could provide pics of the board connections.
The Repeater is a 'chopper' type square wave tremolo. The foot 'swiveler' controls the rate, the LH switch is bypass and the RH switch adds a bit of treble boost.
I have to say, this is an awfully good sounding FF. I had one that I sold and am wishing I had taken some measurements before I sold it.
My question is: has anyone on here taken measurements of Q1 and Q2 from an AM Sunface? Best of all would be if you have gain and leakage measurements from an Atlas DCA. I have a lot of Ge PNPs in appropriate gain ranges, but before I audition them all on the breadboard, I'd like to pull some that measure close to the NKT275s that Mike uses.
In searching here, I didn't get any hits for Univox Square Wave and only one mention of it for Univox SquareWave (did I miss something?), so:
...finally got around to building this one.
The first thing I did was try a bunch of different JFETs. The classic J201 won out. All others gave me a more gated, broken sound.
There were 2 problems. It was way below unity and the fuzz was still mildly gated with too much pick percussion (clickiness) evident. It turned out to much easier fixes than...
Ok guys, WTF? it's not the usual thing what we see in JEN fuzz'es, they usually are close to VOX Tone Bender. Here we see 3 si trannies, two diodes, apparently silicon too.
I bloke I know have it up for sell, he just emailed that pict to me and I'm confused
I've seen lots of info on the Maestro - MPF-1, but never anything on the PS-1 / PS-1A / PS-1B phaser?
Anyone have a schem? Know anything about the footswitch?
It has 3 switches on top for different set speeds, and originally came with a footswitch that connected through a 6-pin Molex type connector on the back of the main unit — it’s pretty rare to find one used still with the footswitch though.
I know Ronsound builds one. I can’t imagine it’s that hard to do. Any pointers where to start?
Here are two pics of this effect. If you look carefully I wrote potentiometers values on the board. Ok here are those pics, I made them using my mobile phone. So they are not that good. Better pics and part values soon I think.
Another oldie from around 73 or so, the Anderton designed Fresh Fuzz. I find this interesting for a couple of reasons, First it is one of the earlier dirt pedals using the JRC4558, it does not have a clipping section but just overdrives the op-amp, and it has true bypass.
I have seen one on line review of this where the sound is described as thin , but from my experience it was anything but. I am sure that the way I ran it had nothing to do with that :roll: It fed into a wah (Morley), phasing,...
:hmmm: not easily :whappen: - look up the data specs for both fets and compare their respective cut off voltages and drain currents etc. :wink:
You will find that they are very different and you will therefore have to change drain and source resistors etc...... :( and the inherent gain of both on 9v supply etc. :slap:
Not saying it cannot be done but THIS circuit was clearly not designed for J201 use :secret:
cheers

A recent discussion brought this unit on top of the pile... This pedal was supposed to be used as a plug-in in old Farfisa organs, and can be used for guitar too.
It's been later included as a built-in version in more recent Farfisa organs.

Hi
I forget where I found this, but it seems to be rare and fetches high prices on Ebay.
As you can see it is an Asian made device and was originally manufactured by someone unknown to me as a stompbox - either as a flanger, chorus, or delay depending on what was required - I have seen the board ( approx 110mm x 65mm), and it has provision for input and output plastic sockets and dc plastic socket too similar to Maxon / Ibanez devices (on the audience end) :wink: - Chandler merely made a large...
Does anyone have or know where i could try and purchase one of these MXR limiters 705 from the 70's???? I have hunted high and low for a schematic for this and i know request's are not the usual thing around here but i was getting desperate and looking for some more information on it as it from what i can gather this unit sounds hot vs some others. Any information would be greatly appreciated. :thumbsup
This one is the old Polish production pedal from the 80's.
Disassembled some time ago but functional so I made gut shots that could be useful for redrawing the pcb and I had hope traced schematic. These production pedals had a funny fet switching and status led was in inverse function when it's engaged and it hums on any adapter. Very noisy pedals, I've seen them a lot in the 90's and kinda miss them 'cause they were cheap. :lol:
My idea was to change old passive components with less noisy...
The Captain just posted a bunch of his diagrams, I think it would be nice to have them around here (Not sure if this is the right sub-forum though).
Baldwin, RotoSound, Park, Vox MkIII, Sola MkIV, Colorsound, CSL. Here:
Maybe it's obvious for you guys but, why do they all look almost the same? Did they just copy to each other? Do they sound the same too? Are the transistors that important to the sound?
1st, hello everyone, this is an awesome site that you have here!
I have a friend who owns a Bi-Phase but does not have the expression pedal.
I'm hoping that I can take a crybaby shell and pot (100KB the pot seems to be) and make it work.
I have the 5-pin cable to plug into the Bi-Phase as well as the proper socket to affix to the wah shell.
I know that the original pedal used an optical circuit.
Can I do this with just a pot?
Does anyone know exactly what i should be doing?
Thanks for any...
Gut shot from a recent ebay auction, but couldn't find any schematic to complement it. It was/is reissued, that I read. This should be an original 1973 one though.
