Incredible - after searching "univox" , "super" + "fuzz", and "superfuzz" theres no thread on this classic effect.
Anyway, schematics can be found

There isn't a specific a specific schem given for grey black vs orange blue but you can see the early version has a .001 cap in the filter. The later ones have a .002. Pretty subtle difference though.

I made designed and built a stripboard layout for this. the original layout is verified (it was a paper design), unfortunately this electronic version isn't as yet.

Here is the one I built:



Tones are footswitchable with a dual colour LED

The "STARVE" knob is some kind of SAG control?

This piece of junk can destroy a man... uh! personal fauvorite!,
Well it has no mistery, there's plenty of info about it on the net, but I agree it deserved it's own topic.
Strongly recomended for every over-the-top-fuzz junkie.

If you have an extra pot laying around I'd say do it. At first it just seems like a combo fuzz/volume control since it affects the volume and gain but the character of the fuzz gets less complex and gates in a cool way. It won't turn it into a fuzz factory or anything but its fun. Use a 5k though. The sound completely dies past that so a 10k or higher will have a large dead zone towards the end of the pot travel.

Realised when I got home from work and started thinking about this that I had already drilled the enclosure for two pots (and also that I didn't have the right pot values so couldn't finish it tonight
). Lucky for me this build is for someone else so when I build one for myself I'll be sure to add this in. I'm quite a fan of gatey fuzzes.

Just play around - I happened to like it.

Is the starve wired as a variable resistor that simulates a dead or dying battery? does it just starve the circuit of voltage?
I fancy attempting this one and will add a starve if I can. Great looking pictures by the way!

Absolutely, just a pot inline with the voltage to the circuit.

Great stuff, Im gonna get busy with this one real soon! Thanks.

To those of you who have built the superfuzz- do you have much trouble with hum/noise? Just finished mine off, and there's a fair amount of hum, which i've never had much trouble with in previous builds. I did have to twist the legs of the base and collector round as I used 2SC828's but the layout was designed for 2N2222's. Could that have anything to do with it?
