The Yamaha APX series of acoustic/electrics is a series of small body and slim neck guitars that provide players with a combination of exceptional playing performance and incredible amplified sound. The series is broken up into three levels. The 500 series, the 700 series and the 900 series. Firstly, all of the guitars in this series are the same size. Starting at the 500 series, these guitars are constructed from ply spruce and nato which make them extremely good sounding and very resistant to moisture changes making them very good as a guitar to be used outside a lot. The 500 series has a 1-way piezo pick up system and is available in many different colors. The 700 series is the same but with a solid spruce top and the first level of Yamaha's renowned ART pick up system. For all practical purposes, the 700 series is a better sounding version of the 500 series due to the solid wood and pick up system. The 900 series is the super supped up version of the 700. It too has a solid spruce top but flamed maple sides and back with an ebony fingerboard for look, comfort and sound quality. The pick up system is upgraded as well to the ART 3 way system which gives users the most versatility and best sound quality by a long shot. We have just received a new shipment of these guitars and would love for you to drop in to try them out.
