Cosmetically stage-aggressive attitude with a spruce top and Yamaha’s own upgraded electric system.
The APX series places emphasis on playability with a stylish thin profile that fits the performing musicians body. One of the worlds most widely sold acoustic-electric guitar, the Yamaha APX500II Thinline Cutaway Acoustic-Electric Guitar has been revamped and refined for a whole new generation of acoustic rockers. The APX500II series now offers new exciting colors, upgraded pickup/preamp and exceptional playability.
This APX shines on stage. With its ultra-comfortable thin-line body and slim, fast neck the transition from electric guitar could not be easier. All-new color variations and updated inlays make sure APX looks as good as it sounds.
APX Soundhole: Oval
The instantly recognizable APX soundhole thickens lower-mid response and gives a more strident, open low end.
APX Body Depth:
80-90mm (3 1/8” - 3 9/16”)
APX’s thin-line body combines incredible comfort, easy top-fret access and a sound perfectly suited to on-stage use with bright, clear mids, balanced highs and controlled lows. Specially designed non-scalloped X-type bracing allows the guitar’s top to sing and maximizes the resonance of the unique body shape for a full, natural tone. With dynamics, sensitivity and clarity built into the design from day one, APX is a guitar not to be underestimated.
Under-Saddle Pickup System
Controls for the under bridge mounted piezo pickup are mounted on the instrument’s side for optimum access. The battery compartment is also located on the side, close to the neck, to provide easy replacement.
System 65
System 65 features an under-saddle piezo pickup developed by Yamaha. Controls include a 3-band equalizer, an adjustable mid-range frequency control, and a precision chromatic tuner for optimum sound tailoring. The system is powered by easy to obtain AA-size batteries that provide a stable power supply for improved sound quality.
