Used Radial Engineering JDI Direct Box

Used Radial Engineering JDI Direct Box in great condition—an industry-standard passive DI built around a Jensen transformer for clean, warm, noise-free signal conversion. It handles instrument and line sources with ease, delivering balanced XLR output, 1/4" input and thru, and a ground lift to eliminate hum. Rugged steel construction makes it road-ready for stage or studio, with wide frequency response and high headroom for bass, keys, guitar, and more.
