The Yamaha TRB1004J is the 4-string version of Yamaha's iconic TRB bass series, first introduced in 1989 as a groundbreaking extended-range instrument and since adopted by countless professional players worldwide. TRB was originally developed to cover the low tonal range beyond orthodox 4-string basses, and the series became renowned for its crisp low-end and comfortable string tension thanks to the super-long 35-inch scale length. The TRB1004J carries that heritage with an alder body topped with figured maple laminate, a 5-piece maple/mahogany bolt-on neck, rosewood fingerboard with 24 frets and a solid brass 4-saddle bridge. Hum-canceling Alnico V single-coil pickups feed an active 3-band EQ with master volume and pickup balancer controls, producing well-balanced, clear sound and access to a wide tonal palette. From studio sessions to live stages, this is a versatile, professional-grade bass for serious players.
