Independent shopping perspective
Fender’s American Ultra II Precision Bass pairs an Ultra II Noiseless Vintage Precision Bass pickup with an Ultra II Noiseless Vintage Jazz Bass bridge pickup, then puts their balance under a pan control. The S-1 switch selects active or passive operation, while stacked controls provide bass, treble and midrange boost/cut, passive tone control, and two selectable midrange frequencies. Its select alder body has sculpted contours; the quartersawn maple Modern D neck carries an ebony 10–14-inch compound-radius fingerboard with 21 medium jumbo frets.
