Get to know them!

The Yamaha TRBX504 4-string bass guitar brings versatility, killer looks, and amazing performance together in a complete package. This sleek-looking, great-sounding bass gives you a comfortable Yamaha body shape and a fast-action bolt-on 5-piece maple/mahogany neck with a smooth-playing rosewood fingerboard. A pair of humbucking pickups delivers hum-free sound while powerful active electronics let you optimize your bass for different playing styles. Factor in the Yamaha TRBX504’s solid hardware and thoughtful design, and you’ve got a great-looking bass that’s ready to rock any stage or studio session.

Comfortable body with progressive styling

One look at the Yamaha TRBX504 4-string electric bass, and you know it means business. A deep cutaway gives you clean access to the higher registers for soloing, while the pronounced upper bout provides balance (and looks cool). The 5-piece maple/mahogany neck has a comfortable and fast-playing profile. The TRBX504 sports a precision fitted neck joint that contributes to the instrument's clear, punchy tone. And the straight string pull of the headstock offers improved tuning stability and reduces overtones. You’re going to love the way the TRBX504 looks, plays, and feels!

Humbucking pickups deliver massive bass tone

Yamaha loaded the TRBX504 with a pair of custom-designed HHB5 humbucking pickups. These pickups house Alnico V magnets and two pole pieces per string for big, open tone without any hum. On top of amazing pickup tone and performance, the TRBX504 has an extremely versatile set of active electronics so you can be ready for any gig. It starts off with an active/passive switch followed by a 3-band EQ, a balance control, and volume. The EQ lets you sculpt the perfect tone for live gigs and studio sessions. No matter what kind of sound you need, the Yamaha TRBX504 4-string bass can get you there in seconds!
