Yamaha BB734A

A four-string bass guitar positioned in the mid to upper price range within the professional BB700 series, crafted for demanding bassists who seek a versatile instrument with a punchy sound and detailed tonal control. The Yamaha BB734A embodies the time-tested BB series with a unique multi-layered body construction, active electronics, and signature neck attachment. This is a serious workhorse for the studio and stage, capable of cutting through a dense mix and adapting to any style.

The body features a multi-layer structure of "alder/maple/alder" with a central maple insert to increase stiffness and emphasize mid-range frequencies for better clarity in the mix. The signature neck joint with screws angled at 45° — a hallmark of the BB series — creates a tighter connection, more effectively transfers string vibrations, and reduces the likelihood of "dead spots." Alnico magnet pickups deliver a rich, "fat" sound with piercing attack.

Specially calibrated active/passive electronics with a three-band equalizer provide detailed tonal control. Switching between modes is calibrated to avoid volume jumps, and in passive mode, the treble knob functions as a classic master tone. An LED indicator warns when a battery change is needed. The versatile Vintage Plus bridge allows strings to be mounted through the body diagonally at a 45° angle or directly onto the tailpiece.

Brass saddles have two sides — rounded for a soft tone and angular for a focused timbre. Other features include a five-layer neck made of maple and mahogany, a rosewood fingerboard, and a 34" scale length. Key highlights include the unique multi-layered alder/maple/alder body construction, signature 45° neck joint for enhanced vibration transfer, Alnico magnet pickups for rich sound, and versatile Vintage Plus bridge.
