Radial JDX 48 Reactor Guitar Amp Direct Box

The Radial JDX 48 Reactor captures the intensity, dynamics and warmth of an amplifier by connecting between the amp head and speaker cabinet. The sound that is similar to a well-placed microphone—but without the typical frustrating inconsistencies from mic to mic.


100% discrete class-A circuitry and a transformer-coupled 'reactive load' capture both the sound from the amp head along with the back electromagnetic impulse from the loudspeaker. This produces a more realistic tone than other company’s resistive pad designs. A multi-stage filter emulates the tone a Shure SM57 in front of a Marshall half-stack.


You don’t have to worry about mic placement, mic type or hall acoustics. The tone in your in-ear monitors remains consistent from one show to the next. Sound-check headaches are minimized.


The JDX also works great on bass, delivering a tone reminiscent of an Ampeg SVT connected to an 8x10 cab. You also get extended low end for deep bass frequencies.

  • Captures sound of both the head and the cabinet
  • Delivers consistent tone - show after show
  • Works equally well on electric guitar and bass
  • Can be used with 48V phantom power or DC supply

Why We Like It

Anything that saves time and frustration—and lets you concentrate on the music—is a winner in our book. And the JDX is absolutely one of those!


If it says Radial, we know it’s well engineered and built to last. There’s less-expensive gear out there, but none better. Radial gear performs gig after gig, session after session, and you can expect years of service—which means our customers love them and we don’t see them coming back for repairs. We always like that.
