"I'm not the kind of guy who gets all 'golden ears' about gear but the JDV direct box changed my mind about just how good a DI can be. It has a clarity of sound and definition that really made me sit up and take notice. Everything is sharper, clearer, and in better focus. The JDV may not be cheap but you hear every penny in the sound."

"I have been extolling the virtues of the Firefly and in fact, I pack it with me on just about every session I've done in the past two years. Most recently on Motown The Musical. You know how important the bass is on those Motown songs. The simple fact is that I love it, and along with my most trusted mics, is brought along on every session. And for Broadway shows, the dual input is a godsend."
George Peterson

"'Gold Digger' is a must-have when I'm shooting out vocal mics. Not only does it allow quick and seamless level-matched A/Bing, but it's entirely invisible and does not alter the sound in any way."

"Finally a product that allows you to use a Mic and quickly A/B different mic pre's without the need of pausing to cut, repatch, listen and repeat. A must-have for recording guitars and vocals."

"In all my years with numerous artists, I've never used a DI that sounded this good and solved problems this easily. When I first tried the Radial DIs it was immediately apparent they were head and shoulders better than anything I had used previously. As a result, we bought 7 so that I am never without them. I use them on acoustic guitars, bass, keyboards and even vocals."

"I've used Radial DIs on all my major touring projects for the last 4 years, with great success. They sound fantastic and are built to last. I'm also a big fan of the Tonebone series, though I have a problem keeping hold of them, always losing them to the first guitarist I come across who has to find just the right sound."
Joe Barresi

Soundgarden, Bad Religion, Queens of the Stone Age

"I much prefer the sound of some guitar effects boxes to rack gear and the Radial EXTC is a perfect interface to my world of pedals. It's easy to set up, blend in and inject some "real" tone into a mix."

"I love my Radial products, since I started using them in 2004 I got my first J48 on a pop tour, I have never looked back. I searched for the perfect DI for years, but Radial products ended my search. I can't even imagine not using Radial products anymore. It's not even a thought. Using them has given me back control of the stage sound."

Jon Burton

FOH Engineer The Prodigy

"After getting a JDX for the guitar it seemed obvious to try it on the bass, brilliant! Deep lows but also capturing the gut wrenching overdriven sound of the amp as well, and best of all - no mic spill!"
Jon Garber

FOH Engineer Rascal Flatts

"The Radial J48s are the only DIs I can trust to sound the same from DI to DI. It's the only DI I will use."

"The Radial JDX is almost too good to be true. The artists hear the sound they are playing and I'm not fighting mic coloration any more. I just plug it in & turn it up."

Kevin 'Tater' McCarthy

"We use lots of Radial products on the Linkin Park tour with two complete backline setups that leapfrog to save on air freight and time. Each backline has 24 Radial DIs for our Protools and keyboard rigs, the acoustic guitar uses a Radial J48 and the bass has Radial JD7s. Sonically Radial DIs are superb and the build quality has proven to stand up to the road. I love my Radial gear!"

"We have Radial DIs on everything. And after several continents and countless dates, they continue to work flawlessly. Radial is the only direct box I use!"
Lee Mayeux

"The Radial JDI is the warmest, loudest and cleanest passive DI that I have ever used. It is reliable, durable and great for any, and I mean any application! And it has a natural analog compression sound and vibe that comes alive the more you push it."

"One thing that has always struck me about Radial is the consistency of quality, no matter the product. The Radial J48 is mind blowing for anything with low or extremely hot gain. Full bodied across the spectrum, the J48 is a new favorite."
Mark Frink

Tony Bennett, Zac Brown Band, Mix Magazine, Live Sound, Front of House

"We use nothing but Radial DI's on the Zac Brown Band tour, and the PZ DI provides the functionality of Radial's Tone Bone PZ Pre into an active DI, Making it the sound engineer's choice for instruments with piezo pickups for live sound, especially mandolins, acoustic guitars, upright basses and other acoustic instruments."

"I have now spent a good year on the road with the SW8 and it's been absolutely brilliant. It always performs, never fails and sounds good. I am so pleased that I am ordering another one!"
Pasi Hara

Monitor Engineer - Serj Tankian and System Of A Down

"Over the past couple of weeks, I used the Gold Digger to switch between 4 wireless vocal channels for Serj Tankian. This allowed me to have enough spare mics handy should he drop one or there would be an issue with RF. The switching was easy, silent and quick and I did not have to notify FOH that we are changing a mic, because it stayed in the same channel with all the same parameters and inserts and such. Great little device!"
Paul 'Pab' Boothroyd

Paul Ramsey

FOH - The Who, Annie Lennox, The Doves and Skunk Anansie

"I used to use delay before and although it works technically, I've done a comparison between using delay and the PhazerBank and PhazerBank wins hands down for sounding more natural and musical. Very easy to use and quick to set up and hear the results with a turn of one knob!" (Notice the PhazerBank right at the top of the rack"
Pavan Grewall

"I use Radial products everywhere I possibly can on stage because they are solidly built and I can always depend on them. Radial makes a wide range of solutions for every audio challenge and they always sound great! We love Radial!"
Randy Kohrs

"The Radial Workhorse has become one of my essentials at Slack Key Studio. The range of functions far outweigh the competition and it is never in the way due to its compact size. The mixer section is among its greatest assets. Once again, Radial knocked the ball out of the park for me as they always have in the past!"
Richard Young

Rob Nevalainen

Tom Petty, Matchbox Twenty, Prince, Def Leppard, Rush

"The two things that impress me the most about the J48 are the great build quality and the great sound. And what that means to me is the J48 is a direct box that I can count on. It works great. It is very transparent, which is important if you're trying to preserve the sound of your 1962 Fender Precision!"
Robert Navarro

Producer Engineer - NFL, Opra, Jimmy Kimmel, Korn, Buck Cherry

"I cannot tell you how amazing the Radial X-Amp is - it was exactly what I needed. The X-AMP solved my Reamping issues in one fell swoop. Re-recording guitars has never been easier. I am a believer!"

"The Radial products are the most transparent, technically comprehensive devices I have ever run across. They are right at the top of my list of 'gotta haves'."
Ross Hogarth

"The Firefly was recommended to me by the incomparable Al Schmidt. I am definitely impressed by the clarity and detail of this Tube DI. Not at all mushy or lacking punch. It has all the attributes I look for in a Bass DI. I also like the many features that have been incorporated. I look forward to trying it on many different sources. I am loving the firefly. It is a GREAT BOX!!"

Russ Miller

Producer, Mixer FOH Sound Engineer - Johnny Marr, Alison Moyet, Lacuna Coil, Rodriguez Cancer Bats

"The JPC is typical of ALL Radial gear, built like a tank, sonically flawless, streamlined in operation and absolutely indispensable. Pro-sumer audio gear is finding its way on to an ever increasing number of stages and studio's around the world, with that comes certain problems with interfacing that gear into a pro audio set-up, noisy "consumer grade" power supplies are a continual problem.

Simon Gogerly

Mixer/Producer U2, No Doubt, Gwen Stefani, New Order, Texas, Manic Street Preachers, Underworld

"My Radial boxes are in constant use, I take them (almost) everywhere. The DIs are crystal clear, I love the JDX for recording amps, the SGI and X-Amp are so useful that I don't know how I managed without them before. On top of that, they're built like tanks!"

Tim Carter

"After working as a musician/recording engineer for 30 yrs, I have finely found a piece of gear that stands up to any Neve console I've ever worked on.. The Power Tube, Power Pre and Q4 eq's are just breathtaking.. I can't imagine anyone not loving these. They just sound beautiful"
Tim Quinby

FOH - Slayer

"All I can say is WOW! Amazing! These things are the best thing to happen to analog since the digital delay! I can't say enough about the difference the Phazers and JDX combo have made! Slayer has always been about big aggressive guitar tones, the JDX/Phazer/mic combo leaves the rest face down in the gutter! Thanks again for such outstanding products!"
Tom Size

Aerosmith, Journey, Steve Miller

"We were using the Countryman and when we plugged in the Radial JDV, we noticed the sound was more clear, more open and more natural. To sum it up the JDV sounds darn good!"
Vance Powell

Aerosmith, Journey, Steve Miller

"I have been using the PhazeQ on tons of stuff since I got it: electric guitar, acoustics and of course bass. It's exactly what you need to get two instruments in phase. I'm having a hard time thinking about recording without it!"

"I use my 3 EXTC's on every recording and mix I do. They are absolutely positively perfect for interfacing low level gear such as pedals, or in my case Tape Echos into my console. Been wanting someone to do this in a 500 space for years. It's just a great tool!"
Zachary Berry

FOH - Clint Black

"The Radial JDX is now a must have in my arsenal! Being able to drive the amp head, not worrying about stage volume and keeping the tone true to as if we had the sweet spot for the mic (on eleven)... FANTASTIC!! It is what is to be expected from the Radial line of products."
Zero Nylin

Quincy Jones, Lionel Richie, Dave Grusin, Steve Miller, Chick Corea, McCoy Tyner

"When mixing live, I try to be true to the on-stage image. But rushed schedules make creating a convincing, pseudo-acoustic image difficult. The Phazer really helps me do the fine tuning. The acoustic bass is easily centered and the piano looses much of the comb-filtering that can occur with multiple mics. The Phazer is quick it is to use. No digi-thinking involved - no sonic signature. It's a no-brainer."
