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.

The TRBX504 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. The neck design combines a fast, ultracomfortable profile with 5-piece maple/mahogany laminated construction for outstanding stability and excellent tone.

Equipped with YGD-designed H5 pickups, the TRBX504 offers 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. The audiophile-grade active/passive circuit on the TRBX504 gives you 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.

Other features include 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. 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. 19 mm string spacing on the 4-string model offers outstanding playability for technical slap or finger styles. Straight string pull from nut to machine head eliminates lateral tension, providing superior tuning stability and reducing overtones. The 38 mm (4-string) nut width gives fast, comfortable playability for any style.
