Put Your Amp's Tones Directly Into the Mix with This Box!

The Radial JDX Reactor guitar amp direct box lets you capture your amp's true sound while allowing a direct feed to a PA or recorder. Using Class A circuitry, multi-stage filtering, and effective cabinet emulation, the JDX Reactor produces a realistic amp sound in a direct feed. If you want a more manageable, consistent onstage sound, or want to use your amp to record without waking the neighbors, this box is just what the doctor ordered. If miking your amp isn't a viable option, or you just want to combine a line signal with a miked one, check out the JDX Reactor!

Radial JDX Reactor Guitar Amp Direct Box at a Glance:
  • Controllable, realistic amp tones - direct
  • What it does
  • Consistent tone

Controllable, realistic amp tones - direct
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.

What it does
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.

Consistent tone
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.
NOTE: The JDX Reactor is NOT a load box - A speaker or equivalent load must be connected to the JDX at all times during use.

Radial JDX Reactor Guitar Amp Direct Box Features:
  • Speaker cabinet emulation for natural tone
  • Direct feed to console eliminates need for a mic
  • Ideal for recording and live performance
  • Works great in conjunction with a miked amp
  • 100% Class-A circuitry
  • Multi-stage filtering

The Radial JDX Reactor lets you inject your amp tones direct!

Works great for bass!

by from Beautiful Fairview, PA
May 16, 2012
Music Background: 40 years semi-pro bassist.
Since the 80's all of my bass amps have had line-outs, and I've rarely been satisfied with the FOH tone. Lately I've been using a '70 Traynor YBA-3 with a GT-6B in front of it, and I love the sound. ... read more [+]The only concern was how to get that sound to the FOH without using a mic or the line-out on the GT-6. I wanted to get the sound of that tube head out front.

I ordered the JDX, and I have to tell you - this thing does everything they say. With my PA channel set flat - I now get the same sound through the PA as I'm hearing from my amp! It's actually difficult for a soundman to screw this up!! Love it.

Radial has a great site that has tons of info on this box; they leave you with absolutely no unanswered questions. close [-]

Sweet!!!

I've been playing live for over 25 years using great amp setups, I'm currently using VHT 2502 amp, JMP-1 & G-force in my rack. The JDX unit gives me a more consistant tone with much faster / easier se... read more [+]tup time. Another huge advantage is less open mics on stage.

Can I get a great sound with good mics, yes, no question, and no the 57 is not in my opinion a good mic fo guitar cabs sorry. The tone this gives is every bit as good as a good mic with proper front end EQ, which you need with any great mic anyway.

Bottom line for the money (200) bucks; Ease of setup; more consistant tone night after night; and less stage noise going into your channel.
Its a no brainer, I'm buying another one today close [-]

Can't beat this little box!

I have been using the Radial JDX for a couple of years now and I could not be happier with how this great little box performs. I have used it on stage and in my home studio and it always does what it'... read more [+]s supposed to do... be transparent. Great features, fantastic build quality and accurate audio. My one and only complaint would be the walwart... just because I don't care for them on any gear. All I tell you is buy one. You will love it.

I use a JDX and a PRODI on my rig in my studio to capture both wet and dry audio from PRS Custom 24. It is nice to have two tracks of clean audio to mix and blend as you desire. close [-]

Awesome Little Box

by Richard Messmann from Brighton, MI

Music Background: Musician
I use this box to split my post amp-head guitar signal to 1) feed rack delay and reverb units via a small mixer and 2) feed a RockCrusher and my cabinet. for a wet/dry stage mix. Like all Radial gear... read more [+], the JDX is built like a brick and does its job without any problems. Small, reliable and effective! Highly recommended. close [-]

eBay your mic

For years I have fought to capture the true tone of my amps. Spent a lot of money on some good mics but was never satisfied. This JDX Box does a fantastic job capturing the amps true tone and sending ... read more [+]the signal to your mixer or A/D converter in the studio.

Plug your amps speaker output to the JDX box and run another speaker cable to you cabinet so the head has a safe load. Then run a XLR cable into your mixer or A.D converter and you are set. Perfect control for you sound engineer. The box also has a ground lift if needed and a phase switch. It also comes with a phantom power wall wart.

I bought two of these, one for my Metro 100 watt Super-lead and one for my 100 watt Marshal Vintage Modern and couldn't be happier. I had a Royer 121 and while that is a great mic this box actually does as good as the Royer capturing the tone. I was concerned about how the box what pickup the details of the speakers but when I used it this worry went away. I also thought I would have to eq up the signal but this also it not necessary at all.

Nothing but praise for this little box, wish I had one years ago. I consider this a must have piece of gear for any guitarist who records or gigs.

Our Customers Say...

I can talk to my Sales Engineer about any piece of equipment, and he always steers me in the right direction. He truly knows what he's talking about, and he never tries to over-sell me on anything. If he worked in the Nashville area, I'd probably owe him about 20 dinners by now!
