JDX 48™ Reactor™ Specifications

The Radial JDX 48 is a direct box that sits between the head and cabinet as if part of the circuit. The intent here is not to produce a faithful reproduction of the signal path, but to combine the signal path with carefully crafted filters to create a 'real world working sound' that engineers can count on for show-to-show consistency. The JDX works equally well on guitar as does on bass and is able to withstand tremendous signal levels without concern.

Specifications are subject to change without notice.
