『Features DiMarzio Custom Pickups』
The rear pickup continues to use the DiMarzio Billy Sheehan Signature "Will Power" pickup, just like the previous model. However, the woofer pickup—the defining feature of the Billy model—features an original DiMarzio pickup designed by Yamaha and co-developed with Billy specifically for this model.
This new pickup, refined from the Yamaha-original woofer pickup featured on the BB714BS, was developed from the ground up based on Billy’s advice.Featuring a humbucker-style design with blade-type pole pieces, and with meticulous attention paid to even the wire gauge and coating of the coils, it delivers ultra-low frequencies with even greater impact than before. At the same time, joint development with Billy—conducted in parallel with the new neck joint method described below—proved successful, resulting in a thinner pickup design.

"Body featuring the 'Spline Joint System,' which accurately transmits string vibration energy throughout the entire body with excellent vibration characteristics akin to a one-piece construction"
As with previous models, the body is crafted from alder, known for its balanced, warm midrange, and incorporates the spline joint system used in the new BB2000 and 1000 models. Thanks to the spline connecting the center where the strings pass through to both sides, this three-piece construction—designed to withstand environmental changes—delivers excellent vibration characteristics akin to a one-piece body, accurately transmitting string vibration energy throughout the entire body.
Furthermore, by incorporating the wood treatment technology “A.R.E.”, combined with the spline joint structure and the I.R.A. treatment described below, we have achieved a body with the finest tone Billy has ever approved.

"Wood Modification Technology A.R.E. (Acoustic Resonance Enhancement)"
A.R.E. is Yamaha’s proprietary wood modification technology that alters the microscopic physical properties of wood to mimic those of a well-worn vintage guitar by precisely controlling temperature, humidity, and atmospheric pressure. This treatment has been applied to the body of the ATTITUDE LIMITED3. This process achieves excellent attack and sustain.(The graph shows that low-frequency sustain is increased, the attack in the mid-to-high frequencies is more pronounced, and after the sound attacks, the harsh high-frequency components decay more quickly.) Furthermore, a key feature is that no chemicals are used in the process, resulting in a low environmental impact. The underlying technology stems from our fundamental research into wood as a musical instrument material, built on decades of experience.

"I.R.A. (Initial Response Acceleration) Treatment"
This technology applies vibrations at the optimal frequency specific to each instrument while it is tuned, thereby reducing stress between the paint, adhesives, wood, and parts, and making the instrument "easy to play" right from the moment it is new.

"Neck Joint"
Previous models were secured using four wood screws from the back of the body and two inside the body, all of varying lengths. Billy is a player who frequently uses “neck bends” to control pitch by bending the neck itself, so further improving joint strength was a key focus in the development of this new model.
The new neck joint, which incorporates an additional 45-degree angled screw, applies force not only vertically but also horizontally to pull the neck toward the body. This not only achieves the desired joint strength but also improves the efficiency of vibration transmission between the neck and body, resulting in a tighter sound.

"Certificate of Authenticity Signed by Billy"
Included with this instrument is a certificate signed by Billy himself, certifying that it was produced at Yamaha Music Craft, where it underwent final adjustments by skilled craftsmen and an I.R.A. treatment process.
