Fuzz Face Clone - wrong mounting?

[venom02]

Hi everybody. I'm quite new to DIY, and after a couple projects i decided to start with a Fuzz Face kit. I soldered all the components following the wiring diagrams here: http://diy.musikding.de/index.php/das-face-silicon.html
The problem is that the fuzz does not work. The sound passes through the pedal when it's off, but when i turn it on, the LED lights and the sound mutes.
I tried to figure out if there's some mistake in the wiring process but i did not found anyone. how can i test if i damaged any components on the PCB? Could i broke the transistors while soldering them? Here's some pictures just in case anyone can spot any obvious error.

Honestly it's probably something simple/small that just hasn't been noticed yet. I'll check out the pics and see if I spot anything.

it could be anything. could be the stomp wiring, the wires that go to the board, or something on the board is not right. I don't know what you have for tools and test equipment but I would test the board without the box. you only need 4 wires. V+ G IN OUT. plug in your guitar and see if you get anything to the amp. if it works then you can go an put it in the pedal.

already solved. i was told to trim the pot and it worked (that's new to me)

yeah you can do it by ear or you can use a meter on the collector of Q2 looking for 4.5v or -4.5 (pnp)
