You're the bedrock of your sound. The foundation. The fundamental. You need an instrument that's designed and built to be the core of your music. TRBX combines advanced design, precision engineering and time-honoured craftsmanship to create a bass that doesn't compromise on comfort, tone, playability or road-ready durability. Excellent Electronics 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 your performance clean and noise-free while the integral thumb-rest provides unrivalled playability. TRBX300 models feature Yamaha's exclusive Performance EQ active circuit with five performance-tuned full spectrum EQ curves optimized to give instant access to essential sounds along with powerful 2-band master equalization to shape and define your tone. Sculpted Body TRBX features a sculpted solid mahogany body, with a mass-optimized 3D design for the optimum balance between tone and comfort coupled with perfect weight distribution. Neck Design TRBX's neck design combines a fast, ultra-comfortable profile with 5-pc maple/mahogany laminated construction for outstanding stability and excellent tone. TRBX 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 perfectly balances strength, vibration transfer and upper-fret access. Hardware 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. 18mm string spacing on the 5-string model offers outstanding playability for technical slap or finger styles. Straight string pull from nut to machine head eliminates lateral tension, providing superior tuning stability and reducing overtones. 38mm (4-string) or 43mm (5-string) nut widths give fast, comfortable playability for any style.
