Wow! That looks killer! 

What are you using as a power supply?

I only had some issues with them having trouble with my file formats. It seems they can do a good job if you give them exactly what they ask for. I'm still not sure what the problem was that they were having. I had to re-create my artwork, the exact way I originally made it, and then it worked. Go figure. Otherwise there is no tech help from them. The final product came out really nice though.

Yep...same thing just not board mounted anymore

I'm out of suggestions too. Give me a few days to build and verify one of the boards I have in stock and if it passes I'll send you and Pietro a new board. If I run into problems I'll order fresh ones from OSH Park.

That's mighty kind of you. Let me know how it goes

I pulled all of the components between C5 and Q6. Checked them all and they are all functional. Just for the hell of it I replaced them all. Still same issue. Not sure where to go at this point.

Here's a gutshot of my SuperFuzz proto

This is the layout that I have.

Pulled the CLR and the LED just for grins and no change.

I'm losing signal somewhere between C5's negative and Q6's base. I just can't figure out what our why 

I don't have mine available right now to look at but I'm sure it is a different layout than Cody's.

As far as I can tell, it looks correct. That being said, it's difficult to say for sure with it fully populated. Here's something else that's strange, if I turn the expander pot fully counterclockwise it turns the LED off.

Yes I have it in correct 

So I had a minute to play around and found that c5 output to the balance pot I get signal at lugs 1 and 2, not 3. From the schematic it looks like lug 1 should be going to ground and not lug 3. Right?

Hmmm....so C5 negative to C6 positive did not work. I checked and the pad for lug 2 is grounded. I attempted to bypass this by connecting the positive pad of C6 to Lug 2 of the pot and pulling the lug 2 leg completely from the pcb. Still no luck. It appears that the positive pad for C6 is also connected to ground somehow. Sounds like a similar problem as the other guy who posted in a separate thread has. Checked all of my solder points and no bridges. With it fully populated this is going to be a bear to find where ground is tied in. Rutger, any chance you can probe around an unpopulated board to check for this? Thanks!

The Schematic is here

Populaed a Nucleon Super Fuzz and I get no signal. I probed it and found the signal loss is between lugs 2 and 3 of the 50kb Expander Pot. Bad Pot? Nope, switched it out and same results. Re-Flowed solder joints, same result. Here are my voltages

Q1: C 144.2mv / B 0.684v / E 5.33v
Q2: C 4.79v / B 5.37v / E 9.15v
Q3: C .3mv / B .1mv / E 9.08v
Q4: C .1mv / B .629v / E 15.8mv
Q5: Unstable
