BB1025X has employed a 3-piece body structure with which its bridge is placed on the center piece in order to translate the maximum amount of string vibration to the body. Instead of simply gluing wood pieces, we insert a Maple plate, called "Spline", into a slot on its joint sections. By doing that, Yamaha has succeeded in obtaining as much body vibration as 1-piece body with this 3-piece body structure.

In Diagonal Body Thru Stringing, strings are angled 45 degree at the saddle to reduce the stress and secure their tension. Moreover, because the attachment area of strings to saddles is larger than conventional vertical stringing, much better transmission of vibration is obtained.

Both front and rear pickups are specially invented for this particular series. Pursuing ultimate passive sound, "Open Face Pickups" are used to cope with even aggressive picking of rock players.

These necks consist of Maple and Nato. It provides durability and prevents necks from warping and curling.

Nickel Silver is selected for nut. It is the same material with fret wires. Unlike conventional bone or artificial ivory nut, it gives the same sound quality and feeling even when open notes are played. For any bass players it is a crucial part of well-defined low end.
