Chapter 3 discusses pickup and circuit modifications. The difference between shorting and opening a coil is explained, with shorting being less likely to result in complete sound loss in case of a switch failure, but potentially degrading sound quality due to electromagnetic interference and mutual induction.

The chapter also covers various switch types, including series/parallel switches, which allow for switching between two coils or pickups, and phase switches, which reverse the phase of one pickup to create a "phase-out sound" with canceled low frequencies.

Additionally, bypass switches are discussed, which can be used to bypass internal preamps, volume, or tone controls, and ON/OFF switches, which can be used to instantly mute the sound. The switches are explained with diagrams, including the wiring for a tap line-equipped single-coil pickup, series/parallel switches, phase switches, bypass switches, and ON/OFF switches.
