Spruce remains the most popular wood for acoustic guitar tops, mainly due to its pristine tonal clarity. Meranti back and sides provide a warm and balanced tone. The Nandu Wood fretboard provides a rich and warm tone. The Nandu Wood bridge transfers string vibration directly to the body, delivering a natural and warm tone. Ibanez Advantage bridge pins really are an advantage over old-fashioned pins. Advantage pins are easier to take out and easier to put in than standard pins. A special bulb-shaped end makes the pin easy to grip and also prevents the pin from being pushed in too far. Best of all, with Advantage the pin and string stay put.
