An alder body combined with a high quality maple top, a 5-piece neck, & its rosewood fingerboard. It has a slightly longer neck for better string attack feel and better bass definition.

TRB was born as a versatile 6-string bass guitar along with the greater involvement of synthesizers in music in end of 1980s. TRB has been developed to cover low tonal range with a 6th string (low B), which could not be reached by orthodox 4-string bass, and also the 1st (high C) makes possible for advanced players for further improvisation and expression.TRB has employed a longer scale length of 35" to increase crisp tonal character in low range and great feel for string tension. TRB's low-noise PU and 3-band active circuit produce well-balanced clear sound and provide access to a wider range of tonal possibilities. As a result of Yamaha's countless efforts for innovation, TRB has been supported by many professional musicians since its debut in 1989 and become an icon of a 5 and 6-string bass in the world.
