The Ibanez PCBE12MH is a Grand Concert body style acoustic/electric bass with Mahogany top, back, and sides for a warm, full tone. While the Open Pore Natural finish enhances the instrument’s natural beauty, it also contributes to the sound quality. Thick finishes can impede the vibration of a guitar’s body, choking the instruments tone and projection. The lightly applied Open Pore finish optimizes sound vibration and allows the bass to realize its full sound potential.
