I've built many guitars and wired them with just a piezo pick up. Sounds great and is easy to do, with my limited electrical skills. I tried to take my builds to the next level by wiring a volume pot over the weekend. It works but there is a slight buzz. If I touch the metal on the jack it goes away, so I need a better ground. Anyone else have this problem? How can I fix it?
Agreed with Henry. Bad solder. Been there. Done that.
You know Wade, I do that but I thought that the metal the case is made of resists solder. That or has some coating from the manufacturer to resist corrosion. I dunno. I sand it up.
Also I find that the case will absorb heat too fast and the solder won't adhere/bond well enough. Again, I dunno.
Bad pot? I've had that happen by applying too much heat before. Somehow it burns it up inside. How hot is the iron and/or did you have to use excessive time soldering?
