What Taylor say:
"If you’ve been following Taylor, you probably know that we recently introduced a new bracing pattern called V-Class bracing. Developed by master guitar designer Andy Powers, this new design revoices the acoustic guitar by changing how the guitar’s top vibrates.
The new V-shaped bracing creates stiffness along the centerline of the guitar (parallel to the strings) and flexibility across the soundboard, allowing both sides of the top to vibrate in an orderly fashion. That rigidity generates greater sustain, while the increased flexibility of the top produces more volume and power. Likewise, that even, orderly vibration pattern resolves the clashing sound waves that we perceive as imperfect intonation, where sour notes and dissonance might arise out of certain chord voicings and note patterns along the fretboard."
