[SOLVED]Der Muff Ram's head, nothing but white noise when on

Hi!

I built this pedal following all the instructions, and when bypassed, the signal is fine, but when I turn it on, I get nothing but white noise! Funnily enough, that white noise changes in tone, intensity and volume when using the knobs. Any ideas what could be causing this?

Thanks a lot!

I measured voltage to the four transistors, and here's what I found:

t1
e 0,05
b 0,65
c 4,22

t2

e 0,05
b 0,65
c 4,19

t3

e 0,04
b 0,65
c 4,19

t4

e 1,09
b 1,57
c 5,18

I wanted to upload an image of the board, but it seems like I have to put it on another server and link from there. I'll be right back with it!

SOLVED IT!

Turns out, the ground cable from the switch, though tinned, got frayed when I inserted it in the PCB and touched the signal cable. Boy, are these cables finicky!!
