The B344 Series/Parallel Push/Pull Pot is designed for use on Dual-Coil Humbucking Pickups.
The Push/Pull switch lets you choose from Series (Normal) wiring to Parallel wiring to get a single coil sound from your humbucking pickup.
The Pot portion of the control is 500K Ohm and can be used as either a volume control or a tone control for a pickup or as a master volume
or tone control.
All EMG Humbucking pickups feature a 5 wire Connection and have a solderless installation.

The B344 Series/Parallel Control should be thought of as 2 separate components.
The Series/Parallel switching is operated by the up/down motion switching of the pot shaft.
The 500K Potentiometer can be used as a volume or tone for the pickup, or can be used
as a Master Volume or Master Tone Control for the instrument.
It depends on how your instrument is wired.
