FuzzFace clone

[john_guitar]

Hello,

I started to create a FuzzFace clone,

This is the schematic:
http://www.geofex.com/Article_Folders/fuzzface/fftech1.gif

and I have some questions:
I red somewhere that it's better to bind the grounds into possitive voltage. I've done it.
Otherwise I could not get any fuzz sound...
I used 2 BC557C PNP Ge transistors. Are they good?

Also, it doe's not matter whether I connect or disconnect the 0.01μF capacitor. I always get the same sound.
And if I disconnect the input of the 500K taper I still get the same sound, because it goes to ground and all grounds
are connected. Is that right?

And furthermore the 1K taper pot does nothing, I changed it to 470K and not I can hear some increase/decrease
in the Fuzziness.

Anyone that can help me?

Thanx in advance

that is correct. if a pnp transistor is used, the circuit is (+) grnd. If you make the circuit (-) grnd, you should get nothing.

I used 2 BC557C PNP Ge transistors. Are they good?

that is for you to determine by:
1) your ear
2) http://www.geofex.com/Article_Folders/ffselect.htm

Yes, All grounds go to a common point.

There are only 9 components and each is there for a reason and will have an effect. If what you are describing above is
correct, you've wired something wrong. Maybe someone can spot your error if you:
