In Phase/Reverse Phase

This guitar wiring modification shows how to use a double pole-double throw mini switch (DPDT) to get 2 modes from a humbucker: Standard in-phase mode, and reverse phase mode. If a mini switch can not be used, a standard push/pull switch can also be used.Note: reversing the phase of the pickup will only have an effect on the sound if another pickup is also on. When combining the out of phase pickup with a second pickup, the sound will be hollow and scooped out will reduced bass. When reversing the phase of a standard humbucker, the hum canceling will not be affected (still hum canceling).
