Ibanez has completely reimagined the acoustic guitar with their Advanced Acoustic series, creating instruments that push traditional boundaries through innovative design and engineering. These guitars feature the new Grand Dreadnought body shape, which is 5% larger than a standard dreadnought, resulting in increased volume, richer tonal qualities, and more powerful low-end response. The series represents years of dedicated research and development, with every aspect designed to provide a richer, brighter, and louder tone alongside an unprecedentedly wide dynamic range. At the heart of these instruments lies the revolutionary X-M Bracing system, developed through extensive trial-and-error testing to achieve optimal sound projection for stage performance. This carefully engineered bracing features scalloped X-bracing combined with strategically positioned tone braces and finger braces that efficiently transmit string vibration from the bridge throughout the body. The result is clear bottom end and crisp treble response with a refined warm mid-range, all while maintaining exceptional dynamic range and high responsiveness. The Advanced Acoustic series also features a newly designed headstock that combines form with function through its tapered shape, which reduces weight while ensuring straight string alignment for enhanced tuning stability and reduced neck twisting. Additionally, the deep straight cutaway from the 18th fret and shaved sides provide remarkable access to the upper frets, making these instruments as comfortable to play as they are powerful in sound.
