The Yamaha TRBX504 features control for master volume, balance, 3-band EQ, and an active/passive switch for maximum flexibility.

Pickups

YGD-designed H5 pickups are defined by a clean, open tone perfectly matched with the flexibility of the active/passive preamp design. Its quad-polepiece design and Alnico magnets give them the power to drive the active circuit, and the sensitivity and subtlety to capture every nuance in passive mode.

Electronics

Featuring 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, and tone-switching circuitry mode, which 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 an LED installed on the back panel gives an instant indication of a low battery to prevent sudden power loss during performances.

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 5-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.
