3-ply alder/maple/alder body construction

The new BB series features a 3-ply alder/maple/alder body construction. The hard maple sandwiched between the alder on both sides enriches the midrange and produces a resonant tone that blends seamlessly into the band’s sound. Furthermore, the use of maple for the body allows for direct sound transmission to the maple neck, reducing sound loss between the body and neck and ensuring that string vibrations are reliably captured.
Miter Bolting for a Secure Neck Joint

We employ a miter bolting system that adds two screws securing the neck end at a 45-degree angle from the body’s back, in addition to the four screws that fix the neck vertically from the body’s back. This firmly bonds the body and neck, producing a powerful resonance as if they were a single unit. Compared to a standard bolt-on joint, this design minimizes energy loss from string vibration, delivering rich sustain and overwhelming body resonance.
Newly Developed Pickup: YGD Custom V7

Features a newly developed, proprietary pickup. Combined with the alder/maple/alder body construction, it delivers a clear, cutting sound that won’t get lost in a band. Available on the 700 Grade and Pro Grade models.
Active Circuit

The 700 Grade of the new BB allows you to switch between active and passive circuits with a single switch. The active circuit is tuned specifically for the new BB’s well-defined tone. Furthermore, the treble knob of the 3-band EQ functions as the master tone control when using the passive circuit, yet features a delicate design that prevents volume fluctuations during switching.This allows for smooth, stress-free switching with natural tone adjustment. High-quality gold-plated parts are used to minimize the risk of poor contact or sound quality degradation. The battery alert LED on the back panel lights up to warn you when it’s time to replace the batteries, preventing sudden power loss on stage.
Controller Section

In addition to a 3-band active equalizer, the new BB700 grade features an active/passive circuit switch and a pickup balancer that flexibly accommodate the player’s desired tone.
Convertible-Type Bridge & Saddle

The 700 and Pro grades feature a "string-through-body" construction where the strings pass through the back of the body. Compared to the conventional method of routing strings vertically through the back of the body, routing them at a 45-degree angle transmits the energy of string vibration to the body with minimal loss.In the conventional string-through-body method, where strings pass directly beneath the saddle, significant vibration loss occurs at the plate and saddle, making it difficult to transmit string vibration efficiently and reliably. However, by cutting the bottom of the body at an angle and routing the strings at a 45-degree angle, stress on the strings at the saddle is reduced.The differences in the contact points of the semi-circular saddles allow for a wide range of expression, from crisp, clear tones to warm, resonant sounds. The brass saddles on the Vintage Plus Bridge produce deep, rich bass tones, while the steel plate delivers a bright sound. Metal parts such as springs and screws are made of stainless steel to ensure resistance to rust and corrosion.

* We recommend long-scale strings when stringing from the front of the bridge, and super long-scale strings when stringing from the back of the body.
5-Piece Neck

Featuring a 5-piece neck constructed from maple and mahogany, it delivers a crisp, sharp sound. This design prevents warping and twisting, keeping the neck in a comfortable playing condition at all times, while the warmth of mahogany complements the tight sound of maple.
Design Neck
The neck profile has been changed to a thinner shape compared to the previous BB model. This provides excellent playability suited to the modern music scene.
Lightweight Tuners
To match the thinner, lighter body of the new BB, we’ve adopted lighter tuners compared to the previous model. This improves the overall body balance and delivers an optimal playing feel.
