Ground loops cause your guitar to pick up annoying hum or
buzz (sometimes even radio stations!) and can be difficult to
troubleshoot. The best strategy is to choose a central ground
point (usually the back of one of the pots) and make all
other ground wires join here in a star pattern. Avoid creating
loops; in other words, don’t run a ground wire from the first
component, to the second, to the third, and back to the first.
