Yamaha BBP34 MB

Features
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.
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.
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.
The new BB models are equipped with one tone control and two volume control knobs, for versatile sound shaping.
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.
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.
