Classic Guitar Amp Sound - From a DI

Wouldn't it be cool to plug into a direct box that gives you the sound of a guitar amp? Unlike common DIs that simply pass signal to the console, the Radial JDX Direct-Drive delivers the tone and feel of a real guitar amplifier. Think about how freeing that would be, not having to lug an amp to the gig! Here's where the amp simulation magic happens: a series of filters meticulously modeled on a Shure SM57 in front of a Marshall 4 x 12" cab. From there, you have two additional voicing options: a vintage Marshall tube head, and an early Fender Twin. Sweetwater guitarists are amazed and delighted by the Radial JDX Direct-Drive. You will be, too.

You need this amazingly clever device

The Radial JDX Direct-Drive delivers classic 4 x 12, half-stack, and open-back combo tones. On top of that, it gives you a presence switch for added sparkle. Operation is simple. The signal path starts with the 1/4" input jack, with a throughput (in case you'd want to feed an amp). That's followed by a dedicated tuner out, buffered to eliminate pickup loading and noise. Then comes the amp-simulating filters we mentioned. For output, you've got a 1/4" guitar-level out, and a balanced XLR to feed the board. The Direct-Drive is also fitted with polarity-reverse and ground-lift switches. So, there you have it: a DI that outputs definitive guitar amp tone. Quite remarkable. The Radial JDX Direct-Drive - every electric guitarist needs one.

Radial JDX Direct-Drive Amp Simulator and DI Features:
  • Guitar amp simulation in a pedalboard-friendly direct box
  • Eliminates the need to bring an amp to gigs
  • 4 x 12, half-stack, and open-back combo tones
  • Radial's JDX tone shaping for authentic guitar amp tone
Get great amp tone with the Radial JDX Direct-Drive!

Oh My !

I wanted a way that I can record without waking up the.entire house. Able to have quality sound and not just some DI. So I did my research and watched a ton of videos, etc. I purchased this with high hopes and I wasn't disappointed. This box is amazing. Great Fender and Marshall tones. The JDX setting is useful as well. What's huge difference from just a DI or worse direct from pedalboard. I run my guitar thru my pedalboard and XLR to mixer. I'm really impressed with the clean tones from all settings. I'm choosing for now the Fender like with Normal selected. I use pedals for my OD. This is exactly what I wanted. I will have same consistent sound direct in mix. Thanks Radial!

Possibly the best Clean Amp simulator in the world!!

I love tube amps. Period. But I've been searching for ways to getting a good clean tone from a light rig and using a light OD for all my blues/rock performances. Though there are many half decent clean tones to be had from existing digital modellers as sans amp stuff and hacks mehffects, they all seem to be either lacking the fidelity and clarity of a tube amp or cost a fortune and still lack the clarity, lol. And so I was amazed when I heard Sweetwater's demo of this little red box I was stunned to hear how clear it was. So I ordered one. The packaging and presentation of this pedal are spot on. It's bright red, the picture doesn't do it justice! The switches are great too. Connectivity-wise it has everything you'd ever need. It can even double as a Y splitter for your signal as it has two 1/4'' unaltered outputs (THRU AND TUNER) though I'm not sure it was designed for that. Works great though! It doesn't need an output knob because it's designed to have the volume set from your interface/ mixing board. So I connected the THRU to my Orange OR15 full stack miked with an E906 at the edge of the dust cap and the XLR output to my interface. Played with a LP. And now for the tones: the Combo setting in either normal or bright is hands down THE BEST CLEAN SOUND I've experienced without miking a tube amp. Zero noise with a very dynamic response and a great attack that lets you hear every little scrape, ring and reverberation made by your guitar. Left me speechless and with a big ole grin :D. The Stack setting works very well clean too, but it's a different sound then I'm used to for humbuckers. A little warmer (possibly to accommodate pedals and singlecoils better), but a usable sound all the same. The jdx 4x12 setting is in my opinion a pedal setting, as it seems to have quite a prominent mid range and mellow highs. It will take bright gainy distortion boxes very well. I prefer having this minimalist layout for the tone settings, as it saves a lot of time and you get your tones from your guitar, toggling pickups and using the Volume and Tone as you would on a great Tube amp. But is the Combo setting as good as a tube amp set clean? I guess people who don't like pedals and have played small all-tube amps all their life (like me) will still hear a very very slight difference in the clarity. The tube amp has just a little more detail if you listen in. And obviously, the JDX it doesn't have any overdrive without adding a pedal. I'm not selling my tube amp for the studio just yet. But it's less noisy than any amp I've heard. Just dead quiet. Not to mention more flexible, tough as a steel brick and a whopping 77lbs (!!) lighter than my studio rig. It just can't be beaten. I'd have honestly payed double for this if I had to, so hats down to Radial for making yet another ultra high quality, great sounding and down right affordable piece of brilliant engineering. And thanks to Sweetwater for showing the way!

Radial JDX Direct-Drive

We all love the warm sound of a burning tube feeding a broken-in speaker, but let's be honest: They aren't the most dependable creations. The Radial JDX Direct Drive...is a highly rugged DI for recording and a worthy replacement when you don't want to haul your Twin up two flights of stairs....
