Purpleheart fretboard produces a rich mid range with a crisp high end. Ibanez Advantage™ bridge pins - These 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. Spruce top remains the most popular wood for acoustic guitar tops, mainly due to its pristine tonal clarity. Sapele back and sides offer a full-bodied and warm mid-range and a bright tone. The Ibanez T-bar Undersaddle pickup accurately translates that full sound to whatever amplification system you plug it into. AEQ-2T preamp is specifically-designed to adjust the frequencies of a bass and allows operation of the built-in tuner without the instrument being plugged in.
