How to Ground Passive Circuits, Pt. 2 (Plus, Build a Solder Cage!)
Here are four ways to ground individual lugs to pots, two ways to connect ground wires to pickups, and a clever soldering technique developed by my colleague Mark Foley. Welcome back to Mod Garage and to the second and final column about grounding in passive guitar and bass circuits. If you missed the first part, check out "How to Ground Passive Guitar (and Bass) Circuits, Pt. 1," from April 2021. Today we'll discuss grounding individual lugs on pots, which is usually the case on all volume controls, but also on some certain tone pots, depending on how the circuit is set up.
