The TRBX174 represents a price breakthrough for the TRBX range, yet the quality is everything you'd expect from a Yamaha bass.
The 4-control circuit includes controls for Master Volume, Balance, and a 2-band equalizer for creating a more aggressive tone.
Electronics (Active/Passive Selector, Battery Alert）
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. A battery alert LED installed on the back panel gives instant indication of low power to eliminate sudden power loss during performance.
Electronics (Performance EQ）
TRBX300 models feature Yamaha’s exclusive Perfomance EQ active circuit with five performance-tuned full spectrum EQ curves optimized to give instant access to essential sounds, along with powerful 2-band master equalization to shape and define your tone.
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 alongside the sensitivity and subtlety needed to capture every nuance in passive mode.
YGD designed M3 pickups feature oversized polepieces and ceramic magnets for a clear, powerful tone with incredible definition and depth. The hum-cancelling design ensures your performance remains clean and noise-free while the integral thumb rest provides unrivalled playability.
TRBX features a sculpted solid mahogany body, with a mass-optimized 3D design for the optimum balance between tone and the comfort of perfect weight distribution.
TRBX’s neck design combines a fast, ultra-comfortable profile with a 5-piece maple/mahogany laminated construction for outstanding stability and excellent tone.
TRBX uses a precision-fitted bolt-on neck joint for maximum adjustability and a 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.
