Yamaha BB734A Electric Bass Guitar

The Yamaha BB734A is a professional-level four-string electric bass guitar from Yamaha’s BB700 Series, designed for versatile tonal performance, stability and comfortable playability. It features a distinctive alder-maple-alder body construction, combining an alder body with a maple centre section for enhanced resonance and tonal definition. Its traditional double-cutaway design provides comfortable access to the upper frets, making it suitable for studio recording, rehearsals and live performances.

The BB734A is equipped with Yamaha YGD Custom V7 Alnico V pickups in a PJ configuration. The split single-coil neck pickup delivers a warm, full-bodied bass tone, while the single-coil bridge pickup provides clarity and articulation. Its advanced active/passive electronics include a three-band EQ with bass, middle and treble controls, allowing detailed sound adjustment. The pickup balancer blends both pickups, while the active/passive switch provides additional tonal flexibility. A battery alert LED helps indicate low battery power.

The instrument features a five-piece maple and mahogany bolt-on neck secured with Yamaha’s six-bolt miter neck joint for enhanced stability and efficient vibration transfer. Its rosewood fingerboard has 21 medium frets and a 250 mm radius. The Vintage Plus bridge features convertible brass saddles and a steel plate, supporting through-body or top-load stringing. Lightweight open-gear tuning machines improve balance, while the satin neck finish provides a smooth playing feel.
