Ok, the fuzz you have made is positive ground, that means the ground on your circuit board is where the red wire from the DC jack connects.
As for wiring up jack sockets, check this out!
I realised most of the pedals i made in the beginning didn't work was probably wiring them up!
But, after finding this, they seem to magically come to life!  ;)

I just recently completed building the GGG fuzz face silicon NPN version.

bellinom has built a NPN Fuzz Face, threfore it's negative ground.

Holy Smokes!!!

I would suggest to put it up for a couple of days.

Grab a cup ofb coffee and do some serious reading. You first have to get your box wired right. You have to understand the relationship of the jacks, switches, powersource, and board.

By your readings if your board is grounded???

Then it is definitely not to your rings as it is suppose to be.

Please don't take this the wrong way no harm is ment, but... And I of all people know the frustion that can cloud ones mind when trying to work out a bug, but shake n bake electronics isn't the way to go.

As mentioned before their are a lot of good sources at your finger tips. Take advantage of them. After reading it a few times and you still don't get it. Then post a new thread asking for assistance on that subject.

Their are a lot of good people here that  will help you, but you have to understand what is being said.


Since I've breadboarded it I can only blame myself.

But It's Just A Chip!

Q1
*C: 8.59v
B: 8.51v
E: 9.07v  {This will be exactly 0.0v from ground, when connected.

Q2
C: 9.1v
*B: 9.07v
E: 9.07v
  Q1C and Q2B will be the same when they're connected.
  {It's possible that the gain control and Gnd. has a miswire}, the emitter should be about '1k' from ground, it is near the supply rail.
  Using the schematic as a guide:
  At each node: count the connections at a node.
  Measure [to the best ability...DMM's don't measure caps so well] each value connected to that node. Check every node.
  Note that some components have polarity which must be followed.
 
Convention creates following, following creates convention.

Oooops! sorry, i assumed if the black battery wire connects to the socket lugs its positive ground, That theory has been well and truly been blown out the water then!
