Guitar Pedal not functioning at all, no sound created
From your updated picture of the back of your PCB it seems as if no component is connected to any other component. This will obviously not make a circuit. Your problem is that you are not using the same type of PCB as they do in the guide you are following.

You are using what is often called a perfboard where all the pads are isolated. They are using a very special type of stripboard (which I can not link to because the RadioShack website is seriously broken), but here is a picture of a similar type:

Note the difference between this and the type you have chosen.

If you want to read more about the different types, you can find information on Wikipedia about stripboards

Your board is not completely ruined. Assuming you have wired everything correctly, you can add the missing connections by soldering short pieces of metal in exactly the same place as the RadioShack board would connect them. Hopefully you saved all the pins that you cut off from the resistors - they will come in handy now!
