The Radial JDX Guitar Amp Direct Box eliminates the use of a microphone on stage, connects between the head and cabinet with a balanced feed going to the PA.

The Radial JDX Reactor is a direct box designed to capture the explosive dynamics and warm tone of the electric guitar by connecting between the head and cabinet of a guitar amplifier to provide a direct feed to the PA or recording system. 100% discrete class-A circuitry, multi-stage filtering and a unique 'reactive' load all interact with the signal coming from the head and the electro-magnetic 'back' impulse from the cabinet to produce a more realistic rendering.

In use, the JDX improves on the consistency of the guitar signal over a typical microphone, as irregularities of mic placement and varying acoustics no longer play the dominant role on stage. When combined with a microphone, fatter tones can be created by double-tracking and stereo imaging the two signals for more ‘produced' results.
