The TRBX505 5‐string 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.
