The TRBX500 series features controls for master volume, balance, 3-band EQ and an active/passive switch for maximum flexibility. Premium mahogany construction and an ultra-musical active/passive preamp design deliver the flexibility and sheer tonal quality you need to sculpt the perfect sound. Pickups YGD-designed H5 pickups are defined by a clean, open tone perfectly matched with the flexibility of the active/passive preamp design. Its 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 (Active/Passive Selector, Battery Alert) Featuring 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 and tone-switching circuitry mode, which 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 an LED installed on the back panel gives instant indication of a low battery to prevent sudden power loss during performances. Neck Combines a fast, ultra-comfortable profile with 5-piece maple/mahogany, laminated construction for outstanding stability and excellent tone. 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.
