Need help wiring a DC jack to stompbox

About a year ago I made a fuzz pedal off of a schematic from instructables.com. The schematics can be found here:

http://www.instructables.com/id/Fuzz-Pedal/

A couple of days ago I tried soldering together a DC jack to the pedal to hook up to my power supply, but it didn't work. I am quite new at this and I have no clue how to wire a DC jack to a stomp box. How do I go about doing to adding a DC jack to this particular pedal?

Thank you.

Download the "offboard wiring" PDF from here:  http://www.tonepad.com/project.asp?id=35

Great resource to keep!  Check out the diagrams, and you will see how your jack should be wired.

also, welcome to the forum. also, "the technology of the fuzz face" at geofex.com, if you are interested. also, we will be asking for photos of what you have built soon, be prepared. also.
don't make me draw another line.

...And be aware that SOME fuzz faces use a POSITIVE ground.   Not this one, as it uses an NPN transistor. 

Lesson - not every single effect is on a negative ground - MOST are, 99% - but if the thing wanted a + ground you'd need to connect the power differently.

The schematic will tell you if it is + ground.

There's a diagram with pictures in the Beginner project of this site. I believe it's under "Switches,bypass,etc.". Definitely ez to follow. + 1 on "technology of fuzz face" article.

I'm with Mike on the Tonepad offboard wiring document: it's very good.  I use it all the time.  And welcome!

Thanks guys,

I'll try to check out tonepad and get back to you guys if it works or not. It did work with a battery snap, been using the thing for almost a year now. The schematics on the site I posted. Here is the picture link: http://cdn.instructables.com/FNJ/WWOH/GPBDGK20/FNJWWOHGPBDGK20.LARGE.jpg

Here are some pictures of my pedal. Might not be clear, but I can't get the board out any further.

What about the wiring scheme? I did it about a year ago, not really good at this stuff.
