Yamaha TRBX304 BL 4-String Electric Bass (Right-Hand, Black)

The Yamaha TRBX304 BL 4-String Electric Bass is built to enhance your performance with a perfectly balanced, ultra-comfortable solid mahogany body that provides optimum tonal foundation. The performance EQ active circuitry gives instant access to perfectly dialed-in, stage-ready tones, coupled with the expressive control you crave. 


The YGD-designed M3 pickups feature oversized polepieces and ceramic magnets for a clear, powerful tone with incredible definition and depth. The hum-cancelling design ensures a clean, noise-free performance while the integral thumb rest provides unrivaled playability.

Electronics Performance EQ

The Yamaha, exclusive Performance EQ active circuit with five performance-tuned, full spectrum EQ curves is optimized to give instant access to essential sounds, along with powerful 2-band master equalization, to shape and define your tone.


Sculpted, solid mahogany body with a mass-optimized 3D design for the optimum balance of tone and comfort coupled with perfect weight distribution


Combines a fast, ultra-comfortable profile with five-piece maple/mahogany, laminated construction for outstanding stability and excellent tone.

Neck Joint

Precision-fitted, bolt-on neck joint for maximum adjustability and clear, punchy tone. Developed through hundreds of hours of play-testing, the refined neck joint shape perfectly balances strength, vibration transfer and upper-fret access.


The Straight string pull, from nut to machine head, eliminates lateral tension for superior tuning stability and reduced overtones.


Nut widths, 38 mm (4-string) or 43 mm (5-string), provide fast, comfortable playability fit for any style.


A high-mass, die-cast bridge efficiently transfers string vibrations to the body for full, rich tone combined with excellent adjustability and road-tested durability. The 18 mm string spacing on the 5-string model offers outstanding playability for technical slap or finger styles.

Output Jack

The Yamaha metal, plate-mounted standard jack sockets offer superior durability and easy maintenance.
