Axis Fuzz Voltage Problem

Hey all, this is kind of a double post, and i apologize for that, but the other one was under a different title, and was geared towards a bit of a different question, anyway...I am building an axis fuzz for my friend and i was wondering if anyone could help me out with some of the readings i'm getting.  I built one of these for myself last year and it is great, works with all the correct voltages etc.  This one, i'm not sure what is exactly wrong.  I was thinking it might be the resistors surrounding the trannies...

Here are the numbers:

Q1 E= 3.44
     B= 2.85
     C= 3.39
Q2 E= 2.78
     B= 3.38
     C= 5.22

My original build was much closer to what someone had posted the actual Axis Fuzz readings to be:

Q1 E= 4.32
     B= 3.63
     C= 3.21
Q2 E= 2.64
     B= 3.21
     C= 5.87

Q1 is 2N3906   and Q2 is 2N3904

I tried swapping out the transistors and got different readings, but still nowhere near as close as what they should be.  The thing that's also strange is that i like the sound of the new pedal better, it seems warmer, not quite as harsh on the distortion.  But it doesn't have the full drive and level boost that i was expecting.  I wish i knew what was causing the change in sound so i could duplicate it in the future.

Thanks for any help!
