The Advanced Acoustic series represents an important step forward in the long and storied tradition of the acoustic guitar. In what amounts to a fully reimagined acoustic experience, these instruments were designed from the ground up to deliver a richer, brighter, and louder tone, with an unprecedentedly wide dynamic range. With slightly larger than typical proportions, we decided to name this new body shape the “Grand Dreadnought.” This reinvented design achieves a superb, powerful sound, and thanks to the extensive consideration given to the ergonomics, it’s extremely comfortable to play. The Advanced Acoustic series pushes the acoustic guitar to new heights, in a way that promises an exciting new experience for all players. Through a rigorous R&D process spanning several years, Ibanez has reimagined the Dreadnought from the ground up, pursuing the height of rich sound, robust low end, and rich tone. This brand-new body shape is called the Grand Dreadnought. Proportionally, the Grand Dreadnought body is 5% larger than a standard dreadnought, allowing for more volume, richer tone, and more powerful low-end response. It’s also extremely comfortable to play thanks to the extensive consideration given to its ergonomics. After spending years of trial-and-error, Ibanez realized the out-of-the-box X-M Bracing to generate the ultimate sound standing out on the stage. The carefully designed scalloped X-bracing, the allocation of tone braces, and finger braces transmit the string vibration efficiently through the bridge to the body. The X-M Bracing creates the clear bottom and crispy treble sound with trimmed warm mid-range yet provides a wide dynamic range and high response. The newly designed headstock shape is the result of thorough research and investigation. Its tapered shape provides lighter weight, as well as a straight string alignment which enhances tuning stability and reduces any neck twisting effect. Its deep straight cutaway (from 18th fret) and shaved side enable amazing high fret access.
