Delivery, Warranty & Returns Information


Styled in a black finish, the Yamaha 300 Series TRBX304 is a four string electric bass with a solid mahogany body and a bolt-on mahogany/maple neck. This neck, measuring 34" in scale, offers a rosewood fingerboard with 24 frets. The fixed die-cast bridge bolsters sustain and tuning stability.


  • Body  - TRBX304 features a sculpted solid mahogany body, with a mass-optimized 3D design for a balance between tone and comfort, coupled with optimized weight distribution
  • Neck - TRBX's neck design combines a fast profile with 5-piece maple and mahogany laminated construction for stability and tone 
  • Pickups - YGD-designed M3 pickups feature oversized polepieces and ceramic magnets for a clear, powerful tone, with definition and depth. The hum-cancelling design ensures that your performance stays clean and noise-free 
  • Electronics - The TRBX304 features Yamaha's Performance EQ active circuit with five performance-tuned full spectrum EQ curves optimized to give instant access to essential sounds along with a 2-band master equalization to shape and define your tone
  • Neck Joint - The bass uses a 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 balances strength, vibration transfer, and upper-fret access 
  • Bridge - 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 19mm string spacing offers improved playability for technical slap or finger styles
  • Headstock - Straight string pull from nut to machine head eliminates lateral tension, providing tuning stability and reducing overtones
  • Nut - The 38mm nut width provides playability for any style
