Originally developed in the Custom Shop for Hamer® Guitars, a Phat Cat is an actual single-coil P-90 Soapbar that fits under a humbucker cover and drops into humbucker-equipped guitars. The tone is big and fat, er, phat. It uses two Alnico 2 magnets for more sustain and softer attack. Also, the metal covers provide more shielding and noise reduction than standard soapbar covers. For use in any humbucker-equipped guitar. Works especially well in balanced instruments with rosewood, ebony or maple
