GGG Tuned BMP debug help

[Deano]

Hi guys,

I've built a GGG tuned Big Muff for my bass player and I'm having some problems with it. I's quiet and doesn't have much gain.

Here's the readings:

Battery: 7.3v
Q1
C =3.52v
B =0.55v
E =0.022v

Q2
C =7.18v
B =0v
E =0v

Q3
C =3.48v
B =0.55v
E =0.020v

Q4
C =3.48v
B =1.28v
E =0.79v

Bit of a noob, it's only my 4th build. Any help much appreciated before I tear all my hair out!

Sussed out the problem, I had a broken trace near the collector on Q2. bridged it and it works like a dream!  I don't have a bass here to try it with but with a guitar it sounds like a monster! Now... just the clean blend to add to it now!
