Hello,
This is my second attempt for a silicon Fuzz Face but I cannot make it work. When I plug it in I get no sound at all. Nothing!
Veroboard layout
Veroboard layout
I tried reversing the guitar and amp cable and I got nothing.
Reversed the trans in every possible combination and still no sound.
Changed the trans from BC108B to a pair of BC183L and anotehr pair of 2N3904 and no sound.
Checked for continuity between parts on the same row and everything seems ok.
Also the holes split the lines properly and there's no continuity between each side of the holes.
Checked if there is any bridge between lines and there isn't.
Lastly checked for continuity from point to point and every point seems fine.

Voltage of each transistor below and they seem extremely low...
Q1
1.3
0.59
0.0

Q2
3.35
0.98
0.73

One thing I'm not so sure is about Vol3. On the layout it says to ground and I put on row e column 2.

If anyone can provide any insight how to resolve this because it's driving me mad! Thanks folks!

Solved!
I had missed a hole @ row a column 7
