Features
TRBX Electronics
The TRBX300 series features controls for master volume, balance, 2-band active equalizer and the Performance EQ preset switch for powerful, precise tone shaping
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 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.
Body
Sculpted, solid mahogany body with a mass-optimized 3D design for the optimum balance of tone and comfort coupled with perfect weight distribution
Neck
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.

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

Nut
Nut widths, 38 mm (4-string) or 43 mm (5-string), provide fast, comfortable playability fit 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. The 18 mm string spacing on the 5-string model offers outstanding playability for technical slap or finger styles.

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