What Fender has to say
The American Performer Jazz Bass includes the Yosemite single-coil pickups, designed for rich, expressive tones. With flat-staggered pole pieces to increase output and a shellac coating that lets the coil breathe while controlling feedback, Yosemite pickups produce dynamic sounds ideal for any musical situation. The American Performer Jazz Bass also features Greasebucket? tone circuitry that lets you shape your highs without adding bass, preserving your sound. The Modern C-shaped neck sports a 9.5-radius fingerboard that?s comfortable for almost any playing style, along with 20 medium-jumbo frets, allowing you to easily express yourself musically.
