4 String Bass from the TRBX600 Series. TRBX600 is all about the perfect balance of elements. The punchy tone of a 3D scuplted alder/maple laminated body, the timeless looks of a flame maple top, the power of Yamaha’s 3-band active/passive preamp, the playability of our slimmest bass neck. Everything you need, just how you need it. Great tone, outstanding comfort, boutique looks. Zero compromise. 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. TRBX600 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. TRBX features a sculpted alder/maple laminated body, with a mass-optimized 3D design for the optimum balance between tone and comfort coupled with perfect weight distribution. TRBX’s neck design combines a fast, ultra-comfortable profile with 5-pc maple/mahogany laminated construction for outstanding stability and excellent tone. 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. Straight string pull from nut to machine head eliminates lateral tension, providing superior tuning stability and reducing overtones. 38mm (4-string) or 43mm (5-string) nut widths give fast, comfortable playability for any style. 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. 18mm string spacing on the 5-string model offers outstanding playability for technical slap or finger styles. Yamaha’s metal plate-mounted standard jack socket offers superior durability and easy maintenance. Finish: Natural Satin
