513 stands for 5 pickups and 13 sounds. The 513 Mahogany is an updated version of our original 513 Rosewood Model. It features a mahogany neck, rosewood fretboard, updated electronics and includes our patented pickup system providing 13 modern and vintage sounds utilizing 5 proprietary single coil pickups. Other specifications include a 25 1/4" scale length, a special neck joint, 513 bird inlays and an easy to use integrated electronics control package, which includes volume control, tone control and two blade switches. One blade switch is a 5-way pickup selector, and the other is a 3-way mode switch that allows you to select between the single coil, clear humbucking and heavy humbucking modes. This is one of our most versatile instruments that can go from screaming humbuckers to sparkling single coils with the flick of a 3-way.
