I'm still fighting it. I re-wired the LED the other way around and that works now but it is still sounding funky. Its all staticy and when I turn the knobs I don't get all the sounds I have heard in demos, it just sorta cuts out. I can get some fuzz but only when everything is turned up.

Check to make sure you've got the right values in the right spots...make sure caps/transistors/ic's are oriented properly...check your grounds...post a picture?

What's the value of the resistor connected to the LED? My kit didn't have one in it.

doesn't matter too much, anything around 1k-10k will be fine

I have mine all put together but having trouble with the IC and the socket. The IC has 16 legs and the socket only has 14 spots for the legs....so 2 legs will be hanging at the end not touching anything. I tried it each way with the legs overhanging and neither worked. Pedal powers on, LED works and when the pedal is engaged the volume works and that is it. I can't figure the IC out. I emailed Dwarfcraft bc all the pics here seem like the sockets are for 16 pins but mine are not.

you don't have to use the socket for the ic though it is safier to prevent the ic from overheat. just be sure to solder it the right way because removing an ic is practically impossible to do without damaging it or damaging the pcb.

Sorry it took so long for pics, I couldn't find my camera. I don't have a resitor on the LED but it's working fine now(I had it wired the wrong way around the first time). I also swapped one of the connecting wires to a pot because it was to short. I am pretty convinced it is a bad wiring job on my part but I don't really know how to isolate exactly where the problem is. It sonds like something isn't grounded right to me because when I touch the components and the side of the enclosure the crazy unwanted stuff goes away. But I don't know anything about how pedals work so I could be way off base.

Oh, and wanted to mention, I got a socket with 14 prongs as well but I bought one with 16 at Radioshack for $.97

So all 16 prongs need to be touching the PCB? Maybe it just wasn't engaging the effect since it isn't soldered in? I just didn't want to have to solder 16 prongs and then have to unsolder.

The ic has 16 legs, you need a 16 leg socket. Yes all 16 need to be touching the pcb. I wouldn't try using effects that don't have all their parts in place, as this could cause even more trouble. After the socket is soldered in, you can remove/replace the ic as needed. Sockets are useful because you don't have to solder the IC (which could harm it), you can rotate the IC if you put it in backwards, or you can try other IC's for various tonal changes, etc.

Ah, that makes sense. Thanks for the input. I contacted Dwarfcraft and they are going to send out a new socket. The Radio Shack close to my house sucks and they rarely have anything that I need.

Unfortuately Radio Shack is not the DIY haven it was some years ago. Decent selection of cell phones though :facepalm: ...to be fair, they make more money selling electronics rather than parts of electronics.
