Sandspur Fuzz no sound

I build a Sandspur Fuzz everything looks find, and I test all the components before, installed.
When the pedal is bypass, the sound is normal, now when you engage the pedal there is no sound . Here are some pictures of the pedal in question thx

Do you have a multimeter?

Take the black test lead and touch it to the ground connection on one of your jacks. Take the red lead and touch it to the emitter, base and collector of the BC108s, respectively, and record the voltages. Also let us know the value of your power supply voltage.
I posted the pictures
 
Hope this help
This doesn't tell us much since we can't really see what it is you're testing. Have the black lead to ground (either on the black circled pad or wire coming from it below) and the red probe to each of the leads of the two transistors going from left to right. I am also including a pinout of the bc108 for your future reference. From left to right on the board it is emitter, base, collector. Write down each of the voltage readings and post them back here in text format since pics of your multimeter make it more confusing for us.
