The PC12MHOPN is Grand Concert body style Acoustic with Mahogany top, back and sides for a warm, full tone. While the Open Pore Natural finish adds to the Guitars natural, subtle aesthetics, it also contributes to the sound of the instrument. Thick, heavy finishes can impede the vibration of a Guitar's body, "choking" the instruments tone and projection. The light, carefully applied natural Open Pore finish permits the wood to transfer sound more freely, optimizing vibration and allowing the Guitar to realize it's full sound potential. The PC12MHOPN also features a Tortouse Rosette, Rosewood fretboard and bridge with Ibanez Advantage bridge pins for improved tuning stability.
