Fuzz factory

[impulse]

Hello! Please help me. 
I soldered Fuzz factory. I used transistors: Q2 hfe 52, Q3 hfe 75. I tried to install transistors with hfe 70 and hfe 110, but they had a big leakage. For this left with the values ​​of hfe 50 and hfe 70.
I subtracted that for correct sound you need to set a voltage of 4.5 volts on the collector transistor Q3.

I have some questions

1) At what positions the knobs need to measure the voltage on the collector of the transistor. I put the handles "gate, comp, volume, stab" in the middle position; "drive" to the far right.
With these positions on the collector of the transistor Q2 - 5 volts, on the collector of the transistor Q3 - 1.2 volts.
2) What voltage value should be on the collector of the transistor Q2 and Q3?
In my case, on the collector of the transistor Q2 - 5 volts, on the collector of the transistor Q3 - 1.2 volts.
3) How to change the voltage on the collector Q2?
4) How to change the voltage on the collector Q3?
I am a beginner and I am asking for help.
P.s. I apologize in advance for my English

Plug it in, turn the knobs, how does it *sound*?

The Stab, Gate, and Comp knobs on the Fuzz Factory let you change nearly ALL of the DC biases all over the place. Try it and see.

I do not see any "normal" setting--- you turn the knobs until you get the distortion you want.

For a normal setting, set the volume to 9 o'clock, Gate and Stab off, Fuzz from noon to 3 o'clock, and the Stab all the way up. It should clean up with your guitar's volume knob.
