The Yamaha TRBX504 4 string bass is a perfectly balanced bass made of all solid mahogany with a 5pc maple/mahogany laminated, bolt on neck that provides excellent tone and awesome sustainability. Comes stocked with H5 pickups that have a clean, open tone thats 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.

All 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.
