GENERAL OPERATION:
The Pi2 is a phase reversal switch that electronically reverses the phase of the pickup. You must have two pickups on the instrument in order
for the Pi2 to work. Reversing the phase of one of the pickups results in a tone that is typically very thin sounding and dependent upon the type of
pickups, the distance between them, and their frequency reponse. The Pi2 is installed on either pickup of a two pickup instrument.
On a three pickup guitar it is best installed on the middle pickup allowing phasing with both of the other pickups. The Pi2 does not
provide the "phased " sound of Stratocaster* style guitars. That sound is derived from the simple mixing of two pickups in different places on
the instrument. The sound of the Pi2 is very unique. Because the Pi2 is used when mixing two pickups is has 2.5db of gain.

warranty covers only those pickups and accessories sold by authorized EMG Dealers. This warranty is not transferable.
