OVERVIEW

An amp emulator and direct box in one handy pedal.

The Radial JDX Direct-Drive is a unique and powerful device that emulates the sound of a guitar amplifier while doubling as a direct box. Unlike a typical direct box that merely transfers the sound of the pedals to the PA, the Direct-Drive simulates the tone and feel of a real guitar amp, producing a much more realistic sound. In other words, with the Direct-Drive on your pedalboard, you can do a gig without carrying an amp to the club.

The design begins with a traditional .25 in. guitar input and passive thru-put to feed a stage amp. This is then followed by a dedicated tuner output that is buffered in order to eliminate loading on the pickup or noise from the quartz clock. The guitar signal is then passed through a series of carefully sculpted filters to create Radial’s signature JDX tone. This is modeled after the sound of a Shure SM57™ in front of a Marshall™ 4x12 cabinet. The Direct-Drive goes further with two more voicing settings: the first adds a vintage Marshall tube head character to the signal path while the second delivers a tone reminiscent of an early Fender Twin. The two amp tones can be further tailored using a presence switch for extra sparkle. The guitar signal exits the Direct-Drive via either a 1/4" guitar-level output or via a balanced XLR to feed the PA. The direct box output is outfitted with a 180° polarity reverse switch to help phase-align monitors with the stage amp along with a ground lift switch to help eliminate hum and buzz caused by ground loops. The Direct-Drive may be powered using a standard 9V power supply or typical pedalboard power brick.

As with all Radial products, the Direct-Drive is made to handle the rigors of professional touring with 14-gauge steel throughout. This not only helps prevent damage to the internal PCB, it also reduces susceptibility to noise from external magnetic fields.

    Comments about Radial Engineering JDX Direct-Drive Amp Simulator and DI Box Guitar Effects:

    My application requires a quiet/controlled stage volume, so going direct to the PA without using an amp is an essential part of my setup. Prior to switching to the Radial JDX Direct Drive, I used a Behringer GI100 Direct Box with speaker simulation. While this worked, it left me wanting a little more from my tone, especially amp simulation. I am not a fan of the digital simulation boxes and prefer analog solutions if possible. The JDX Direct Drive goes beyond speaker simulation with the addition of two amp simulations. Additionally, the bright switch provides a little more tone tweaking. These adjustments allow me to target the best combination for my guitar and it is a nice improvement over the Behringer. That being said, I find that I need to do some final tone shaping using the EQ controls on the main/house mixer. Since I prefer to send the best tone possible directly from my setup, I will need to add a tone shaping/EQ pedal to my board for final fine tuning adjustments. All in all, the Radial JDX Direct Drive does a good job of providing a very nice speaker and amp sound direct to the PA. It is very clean (not noisy) and the Radial reputation of quality is obvious.

    Radial modeling DI

    Comments about Radial Engineering JDX Direct-Drive Amp Simulator and DI Box Guitar Effects:

    I have used the Behringer Ultra G for many yrs. and it worked good. I also have a Radial stage bug, and other di boxes.. I thought this JDX would be the best, but found the sound dull and I had to use an EQ pedal to improve it. ( I didn't need it on the Ultra G, or Mooer DI; both have speaker sim). It is an active DI so more care had to be taken not to distort the clean signal, because the JDX distorts it more. The 412 cab setting had too much bass added to the signal, so the JDX needs a bass cut switch. In a large concert venue, this might be the best DI out there, but for regular bar gigs not so.
