Ok its been a while but ive (just about) finished my fuzz pedal!
Just need to add a DPDT switch and put it in a box
However...
When i first tried it out with the original diode and the battery plugged in all i got was a lot of static. I messed around with it for a while, checked the schemo, but everything seemed to be in order. Eventually, i used the 1n60 diode that john kindly sent me, and got a nice fuzzy tone. Only thing is, it doesnt need a battey to do this. In fact, if the battery is attatched, it doesnt work at all. So i've accidently created a passive fuzz pedal?
Sweet!
I tried using the original diode (1n4148) passively with the pedal as well, but the sound kept fading in and out, so im sticking with the 1n60.
The tone is pretty good, i ran it through the valve channel on my amp with gain cranked up and got a killer sound
Does anyone know anyhting about passive pedals? I'll upload pics soon in case anyone can see what ive done wrong.

I can't really see what you have done wrong...But something is wrong
You may have fried the first diode or something else, Looks like the board has had a lot of heat.
It could be a solder joint, they should be shinny and volcano shaped, if that makes sense.
Is your soldering Iron tip nice and clean?
Also if you twist the ends of the wires and put a bit of solder on the end they will go through the holes easier.
I think you should snip off the clean half of the board and try again, with new parts. Sometimes doing it over is easier then debugging.
And I would try the 1n4148 again, they sound good when working.

Great work to get a fuzz sound though..and no battery :D

This page shows you a good way to lay out the pcb...http://www.home-wrecker.com/bazz.html

Well i finally got round to sorting out my DIY fuzz pedal. I actually ditched the old one that didn't work properly and started again from scratch. The volume output on it was ridiculous, so i added a couple of resitors on the signal output. I also added an LED
Heres a photo of it with the rest of my setup. I usually run it before any modulation and have it before my multi fx as it doesn't process flanger or anything like that well, but i have another distortion pedal that handles it fine, so no biggy.

Awesome man. Sometimes it is easier to just start again.
What do you think of the tone?

Well I was surprised at the quality for such a simple circuit. It's a bit edgy for a fuzz pedal when used with my musicman stingray which is active and has humbuckers but performs really well with my passive P Bass
