The Radial JDX Reactor guitar and bass DI box design features 100 discrete class-A circuitry. Unlike ordinary DI boxes the JDX also plugs in between the amp head and speaker cabinet allowing it to cleverly capture both the sound from the amp head along with the back electromagnetic impulse from the loudspeaker. This produces a more realistic representation of the entire guitar tone, superior to many other DI boxes. The signal is then processed via a carefully designed multi-stage filter to emulate the tone of a 4x12 half stack cabinet.

Using the JDX delivers greater consistency over a typical microphone, removing variables such as mic placement and room acoustics. This is most appreciated when using in-ear monitoring, as the tone remains consistent from one show to the next. Another advantage is a reduction in setup times and a more comfortable audio feed for the artist.

The JDX Reactor provides quick and easy set up, delivers great sound and provides consistency for both performers and audio engineers alike.
