hi i am currently building the one knob fat fuzz from renegadian's layout gallery. this one http://www.aronnelson.com/gallery/main.php/v/Renegadrian/ONE+KNOB+FAT+FUZZ.jpg.html
and was wondering if this http://www.aronnelson.com/gallery/main.php/v/Toneys-Album/Wiring.png.html is the best way to be wiring everything up. oh and do i need the 2k2 reistor for the LED as i dont have one. any advice is greatly appreciated

That wiring set-up probably works, but this one is easier to follow- http://www.beavisaudio.com/techpages/StompboxWiring/ As for the LED, you will not need the resistor, as that just makes the voltage suitable for the LED, but the switching may be messed up a little bit. However, I'm not sure about that.

Edit- My bad, I interpreted your post as you were going without an LED. The OP is right.

That layout looks good, and yes you do need a resistor around 2k2 since it makes it hard on the LED and it might fry it. Anything a bit more in value will make the LED less bright, it really is all preference.  If you have a couple 1K or so resistors just put them in series to add their value.  Also you can easily test just the LED with the resistor and a battery on its own.

My advice if your just getting into building and want to continue, buy parts in bulk, saves tons on shipping.  Or what I did in a quick pinch, by the big multi pack from radioshack, it has 2 or 3 of most common values in it.

thanks spidermonkey and timehawk.ill try the led and battery tonight also i noticed that the beavis wiring has 2 grounds. do you know could i solder another ground onto the one on the one knob fat fuzz?>

Spidermonkey

The two grounds are just for convenience. As long as what you want to ground somehow connects to the ground on the PCB, you should be fine. (See my edit above.)

^^^

The 2 grounds coming off the board in that wiring schematic is the same ground strip. You can hook up as many grounds from the phat fuzz ground strip as you want.  So any 2 points on the strip will do for the wiring schematic.

cheers guys sorry about the stupid questions but i am a beginer. ive built a booster from a kit and this is my first real build so to speak. ill definatly be buying in bulk from now on

You should use a resistor with the LED to prevent it from burning out.

ok used a reisistor now .....and nothing. there is still a clean signal when the pedal is off but nothing when it is engaged. any thoughts
