Yamaha TRBX604FM 4-String HH Bass, Rosewood Fretboard, Matte Amber

TRBX Electronics

TRBX600 features controls for master volume, balance and 3-band EQ with an active/passive switch for maximum flexibility.

Pickups

YGD H5 pickups are defined by a clean, open tone that’s perfectly matched with the flexibility of the active/passive preamp design. Their quad-pole piece 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 (Active/Passive Selecter and Battery Alert)

TRBX600 models feature an audiophile-grade active/passive circuit for fine, tonal control and extreme flexibility. This 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 the LED low battery alert installed on the back panel helps to prevent sudden power loss during performances.

Body

A sculpted, alder/maple-laminated body with a mass-optimized 3D design strikes the optimal balance between tone and comfort coupled with perfect weight distribution.

Neck

The TRBX neck design combines an ultra-comfortable profile with 5-piece maple/mahogany-laminated construction for outstanding stability and excellent tone.

Neck Joint

Developed through hundreds of hours of 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 a full, rich tone combined with excellent adjustability and road-tested durability. The 18mm spacing on the 5-string model offers outstanding playability for technical slap or finger styles.

Output Jack

The Yamaha metal, plate-mounted standard jack socket offers superior durability and easy maintenance.

This series is all about the balance of elements, and with the punchy tone of a 3D-scuplted, alder/maple-laminated body, timeless looks and the power of the Yamaha 3-band active/passive preamp, the TRBX600 sets a new standard of perfection.
