Product Description

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.

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.

The Radial JDX Reactor is an easy to use interface with a sophisticated internal signal path that includes 100% discreet components, Radial's highly acclaimed class-A signal buffering, transformer isolation and a series of speaker emulating filters. On board functions include input connection from the amplifier head and throughput connection to the speaker cabinet. A ground lift switch allows the engineer to disconnect the earth ground from the mixing console. A polarity reverse is also offered that can be used to phase correct the output when run through stage monitors or simply interface with older gear that may not follow the current AES standard. The Radial JDX is transformer isolated to help eliminate buzz and hum caused by ground loops.

Housed in a 14 gauge enclosure, the JDX features an internal I-beam construction to reduce susceptibility of outside stress that could torque the circuit board and reduce long term performance of the switches and jacks. Two protective zones are created with a unique book-end design that keeps switches and jacks out of harms way. Finally, a full bottom no-slip rubberized pad keeps the JDX from sliding around on busy stages and from falling off ye old Marshall stack when played at 11. The JDX may be rack mounted with a Radial J-Rak or permanently mounted on the rear panel of an amplifier or inside a rack using the Radial J-Clamp.

Features

Guitar amplifier direct box with reactive load

Speaker cabinet emulation for natural tone

Direct feed to console eliminates need for a mic

Ideal for recording and live performance

Usage Examples

Using the JDX with an amplifier:
The Radial JDX connects between the head and cabinet with a balanced feed going to the PA. This set up eliminates the use of a microphone on stage, reducing clutter while providing the mixing engineer with a consistent tone independent of room acoustics, mic placement or bleed from other sound sources.

Combining the JDX with a microphone:
The JDX is connected as described above but a microphone is added for a second channel. The two sounds are then mixed together or spread 'stereo' to create a fatter tone. This setup is often used in the studio to create 'produced' tones.

Using the JDX with a Mic and a Radial Phazer:
The magic of the JDX is fully revealed when combining the JDX's direct feed with a microphone while incorporating the Radial Phazer to phase-align the two signals. This combination lets you dial-in the 'sweet spot' to produce fat rich guitar tones quickly. This is of particular advantage to touring bands that must set up quickly between gigs as they travel from one venue to another.

5 out of 5 (6 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Awesome!"
Overall: a berklee classmate of mine turned me on to this thing. he was in the blues guitar course at the time and was showing off some killer blues tone with his srv strat into a fender amp. i've been unhappy with amp sims and had tried various load boxes with direct outs (including some well favored ones) and they just didn't do it for me. enter the JDX and i'm a happy camper!!! i sent my buddy some clips back and now he wants to buy the guitar and amp i have... lol! the JDX gives me hands down the closest print of what i'm hearing when i play that i've come across, and it comes in a very convenient and reasonably priced package. very happy with this purchase!

"at last - radial engineering saves the day!!! at least if you are an electric guitarist!"
Sound: compared to my berhinger ultra g, well its more of a contrast than a comparison, the jdx is organic, round, and 3-dimensional, whereas the ultra g is flat and piercing. Sounds like a well-miked cabinet rather than a cheap eq filter. with the jdx, turning up the volume makes it sound better, not worse like the ultra g. the jdx is much more dynamic!!! Feature: dead simple to operate. does not have pad buttons. the construction is 1st class. much better components than almost all other D.I.s. Ease of Use: you would need massive brain trauma to screw it up. Quality: extreme reliability, no back-up needed. this pedal is both beatiful and could withstand a bomb blast. incredible design - these guys at radial have excellent ears! Manufacturer Support: but you will not need it. Overall: not expensive considering its about the cost of a microphone, sounds as good or better, and will save you a lot of time.
Style of Music: hard rock instrumental
