Spruce 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 Okoume neck provides greater playing comfort. The Purpleheart fretboard emphasizes the beauty and the rich tonal character of this instrument. The Purpleheart bridge transfers string vibration directly to the body, delivering a natural and warm tone. The Ibanez Undersaddle Pickup accurately reproduces the acoustic nature of the guitar. AEQ-2T preamp is specifically-designed to adjust the frequencies of Bass and Treble, and allows operation of the built-in tuner without the instrument being plugged in.
