Soldering Pot Backs
This is part 2 of the video series on wiring up guitar electronics.
All the metal parts of the guitar need to be tied to a common ground, including the pot bodies. If you don’t do this, you end up with noisy ground problems. A good place to wire the ground is to the back of the pots.
There’s a few tricks for successfully soldering to the backs of the pots. First up is a hot iron. I’ve tried with a 25w iron, and it just doesn’t cut it. 40w works, but be sure to let it heat up for 10 minutes or so before trying. I use this cheap Radio Shack iron which switches between 25 and 40w. Also, you need to roughen up the surface of the pot to get off any oil or grease, and to give some good grooves for the solder to adhere to – I just use 100 grit sandpaper. Take a look:
