The APS-2 Alnico II Pro Flat pickup combines the same coil design as its predecessor, the APS-1, with rod magnets of equal length raised above the flatwork. The flat magnet pattern provides the balanced field necessary for an even response using today's strings and flatter neck radii. The Alnico II magnets' softer magnetic field creates a warmer, smoother sound and eliminates the brittle, glassy sound associated with new instruments. Reverse Wound Reverse Polarity (RWRP)
