TRBX Electronics
TRBX500 features controls for master volume, balance and 3-band EQ with active/passive switch for maximum flexibility.

Pickups
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.

Electronics (Performance EQ)
TRBX500 models feature an audiophile-grade active/passive circuit for fine tonal control and extreme flexibility. The advanced design offers a level-matched output whether in passive or active mode and tone-switching circuitry that seamlessly moves from treble control to master passive tone. High-quality gold plated parts are used for key signal chain contacts, providing increased conductivity and reliability and a battery alert LED installed on the back panel gives instant indication of low power to eliminate sudden power loss during performance.

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
TRBX’s neck design combines a fast, ultra-comfortable profile with 5-pc maple/mahogany laminated construction for outstanding stability and excellent tone.

Neck Joint
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.

Headstock
Straight string pull from nut to machine head eliminates lateral tension, providing superior tuning stability and reducing overtones.

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

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. 18mm string spacing on the 5-string model offers outstanding playability for technical slap or finger styles.

Output Jack
Yamaha’s metal plate-mounted standard jack socket offers superior durability and easy maintenance.
