Here's what Yamaha say:

Music isn't just something you “do” anymore— it's your life. Every time you get on stage or hit the record button you've got to feel content in the knowledge that you’re playing an instrument with the versatility, durability, and superb sound that will guarantee your performances are consistently on point. Combining the crisp, penetrating tone, and serious flexibility of active pickups with the punch and sustain of a 6-bolt miter neck joint, the 700 models can be relied on to deliver an extraordinarily versatile sound that you can adapt to any genre or environment.

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.

Active Circuit

The new BB700 models feature a specially tuned active/passive circuit for fine tonal control and extreme flexibility.
This updated circuit has been retuned for the BB for a crisper tone and improved mids via a level-matched output whether in passive or active mode and tone-switching circuitry that seamlessly moves from treble control to master passive tone.
High-quality gold plated parts are used for key signal chain contacts, providing increased conductivity and reliability and a battery alert LED installed on the back panel gives instant indication of low power to eliminate sudden power loss during performance.

Control

The 700 models feature active pickups with a 3 band EQ, a pickup balancer, and an active/passive switch, for enhanced versatility and flexibility when shaping your sound.

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. Strings can also be set to the tail end of the bridge, which comes equipped with a convertible saddle that can be adjusted to 2 different angles for more precise tonal shaping and feel. The rounder side of the saddle gives a slightly softer sound, while the more angled area produces a slightly tighter one.
The brass saddle of the Vintage Plus Bridge delivers a slightly deeper low-end, and the steel bridge plate offers a brighter tone. All screws and springs are made of stainless steel to guard against corrosion.

Five-piece Neck

The new series features a 5-ply maple and mahogany laminated neck, in a bolt-on design that delivers a sharp attack, and quick response. This durable construction resists warping and twisting and adds the tight, penetrating character of maple combined with the warmth of mahogany to the instrument’s tone.

New Neck Shape

The New BB models feature a slightly thinner neck than previous BB basses, improving playability and feel for both modern and traditional players.

Lightweight Tuners

Lighter weight tuners offer a better balance and complement the overall feel, providing a perfect match for the smaller, lighter body of the new BB.
