Here's what Yamaha say about the APX600:

Part of the world’s best-selling series of electro acoustic guitars, the 600-series, the Yamaha APX600 Electro Acoustic Guitar is noted for bringing together the ingredients that are important to players; performance, value and reliability.

In addition to these core values this model also offers a spruce top finished in a range of finishes that really stand out from the crowd, while the nato back and sides complete the construction of the Yamaha APX600 Electro Acoustic Guitar’s comfortable thinline body to offer bright mids, balanced highs and controlled lows. The bracing of the APX600 has also been recdesigned so that you get a better bass response which is ideal when using the built in system 65 pickup system.

The APX600’s body also benefits from a cutaway, making the upper registers easier to access. Furthermore the guitar’s natural tone is emphasised further and resonance maximised, with the top’s specially designed non-scalloped X-type bracing.

MULTI-FUNCTION PICKUP
The Yamaha APX600 Electro Acoustic’s powerful, dynamic tone is translated perfectly through your amp, thanks to the inclusion of the new and improved Piezo pickup system and System 65 preamp. This low-profile system is discreet but offers a tuner, 3-band equalisation - including selective middle frequency, and master volume.

The Yamaha APX600 Electro Acoustic Guitar is an instrument you can rely on and is ideal for any level of player looking for a solid performer.
