The TRBX504 bass guitar features premium Mahogany construction and an active/passive pre-amp design that delivers the flexibility and sheer tonal quality to sculpt the perfect sound for your music. The pickups have a quad pole-piece design and Alnico magnets that give them the power to drive the active circuit and the sensitivity and subtlety to capture every nuance in passive mode. High-quality gold plated parts are used for key signal chain contacts providing increased conductivity. It also has a 5-piece Maple/Mahogany neck, battery alert LED, high-mass die-cast bridge, straight string-pull from nut to machine head, and metal plate-mounted jack. Translucent Black finish.
