Made in Japan, this is the ultimate BB, featuring an Alder/Maple/Alder construction treated with Yamaha’s unique IRA technology, a six-bolt miter neck joint, and a diagonally strung convertible bridge. Alder/Maple/Alder Body Construction The new BB features an Alder/Maple/Alder multi-laminated body construction. The hard maple center increases body stiffness and accentuates midrange to cut through the mix of a band, and allows a more uniform transmission of vibrations between the body and the maple neck for unparalleled resonance and sustain. 6-bolt Miter Neck Joint Miter bolting holds the neck closer and tighter to the body fusing these two separate components into one. Compared to a conventional bolt-on joint, miter bolting offers more efficient transfer of string vibration throughout the body, for improved sustain and outstanding resonance that brings every note to life. YGD Custom V7 Pickups Alnico magnets produce a fat yet penetrating tone that works in combination with the unique Alder/Maple/Alder construction of the 700 and Pro models for an organic, well-defined sound. Control The new BB models are equipped with one tone control and two volume control knobs, for versatile sound shaping. Convertible Bridge and Saddle for Precise Tone Shaping: Vintage Plus Bridge The 700 and Pro are equipped with the Vintage Plus Bridge, which incorporates “Diagonal Body Thru Stringing,” where strings are angled at the saddle and pass through the instrument to the bridge at a 45o angle, as opposed to the traditional vertical stringing method which places more stress on the strings. Diagonal Body Thru Stringing significantly reduces this stress while transferring string vibration to the body reliably and efficiently.
