Hey everyone,
I recently built the one knob fuzz kit and I’m having some issues. My LED works and my guitar’s signal passes through when the effect is switched off, but when I engage the switch my signal cuts out and all I hear is a light static-y sound that gets louder when I turn the pot clockwise. The LED changes colors as it’s supposed to.
I am not the most technically adept person but I have a feeling my mistake lies in the wiring from the DC jack to the 3DPT board, or from the 3DPT to the main circuit board. I didn’t quite know what to do with the G terminals on the bottom left and right corners of the 3DPT board. Also, I realize I soldered wires through the printed side of the board instead of the bottom, but from my limited understanding I don’t think that should matter. I also initially soldered the pot to the wrong side of the board and had to desolder and move it to get everything fitting in the enclosure. These last few points are probably not relevant but I’d rather include too much info than not enough.
Thanks!
Hi and welcome,
It seems at a glance that the wiring layout is good.
I know it is hard when you are starting but getting practice with how you want to solder wire is key. So when you look at the photo I pointed at a couple key places you will want to reflow and make sure there are no loose wires. Also you need to make sure you do not have cold solder joints or a ball sitting on top of a pad. Take your iron with a fine conical tip and reflow and work the wiring to a better position while also fixxing solder balls or cold joints by letting the solder flow into the joint.
Be very careful not to damage the solder pads when doing this.
You should actually make sure your wire is flush to the pads and solder from the other side.
Apply the same technique to any and all other trouble looking areas anywhere else including the back of the main circuit board.
This is a good learning experience for you and once you get one pedal right then it works the same for all the rest.
Good luck.
Thanks for the words of advice, Barry. I’ll desolder those wires and solder them from the other side, and then I’ll fix those other problem areas.
I redid all the wiring to go through the other side of the board and touched up those ugly joints on the switch. The pedal is operational! Looking forward to applying these lessons learned on my next build. Thanks again Barry.
