From the tip of the headstock to the bottom strap button, the Yamaha TRBX504 bass is a great value, but more than that, it's a great instrument. Equipped with all of the features a committed student needs in order to advance on his or her instrument, the TRBX504 sounds and plays great, and offers a variety of sounds that are appropriate to a variety of playing styles.

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.

Pickups
YGD designed H5 pickups are defined by a clean, open tone that's perfectly matched with the flexibility of the active/passive preamp design. Their 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
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.

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.

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. 19mm string spacing on the 4-string model offers outstanding playability for technical slap or finger styles.

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

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

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