As one of the most versatile guitars in the PRS lineup, the 509 harnesses the power of 5 pickups to deliver 9 uniquely musical tones. The 509 starts with a 5 single coil platform - with the outside four coils grouped as humbuckers. An innovative switching system (a 5-way blade switch and two mini-toggle coil-tap switches), gives players an array of humbucking, singlecoil, and blended tones.
Unique appointments include a longer 25.25" scale length which adds upper harmonic sparkle and the PRS Gen III Patented Tremolo which provides impressive sustain.
