  • Radial JDX Reactor Guitar Amp Direct Box Details

    The Radial JDX Reactor is a direct box designed to capture the explosive dynamics and warmth of an electric guitar amplifier by connecting between the guitar amp head and speaker cabinet. This delivers a sound that is similar to a well placed microphone while eliminating the frustrating inconsistencies.

    The design begins with 100% discrete class-A circuitry and a transformer-coupled 'reactive load' that captures both the sound from the amp head along with the back electromagnetic impulse from the loudspeaker. This produces a more realistic rendering than the usual resistive pad offered by other manufacturers. The signal is then processed via a carefully designed multi-stage filter to emulate the tone of a 4x12 half stack cabinet.

    In use, the JDX delivers greater consistency over a typical microphone as irregularities such as mic placement and varying acoustics no longer play the dominant role on stage. This is most appreciated when using in-ear monitors as the tone remains consistent from one show to the next, resulting in shorter setup times and a more comfortable audio feed for the artist.

    Although originally designed for guitar, the JDX has also become a favorite on bass. The clarity and punch in the lower mid range delivers a tone that is reminiscent of an Ampeg SVT connected to an 8x10 cabinet. On guitar it sounds as if you have a Shure SM57 in front of a Marshall half-stack.

    The JDX Reactor is easy to set up, delivers great sound and is consistent.
