"We recently checked out the Radial JDX Direct Drive in preproduction rehearsals. The Direct Drive blew everyone away. When running the DI out from the Direct Drive, we got 100% repeatability of the signal from the Direct Drive. I used the thru out into a combo amp to generate feedback, but we didn't even mic it up as we were all so happy with the sound from the Direct Drive. It’s now permanently on my pedalboard. Thank you Radial."

"The Radial SW8 is hands down the best switcher for a playback rig and I use it with all the big artists. There's no other device like it out there and it's the industry standard. No matter what DAW or interface you use, this is the piece to have as it's trustworthy and will never fail you. Your sound will be pristine and clean and it's the one piece you never have to worry about. With the playback rig being one of the most important parts of running a show, I'm always confident the SW8 gets the job done."

"After working as a musician/recording engineer for 30 years, I have finally found a piece of gear that stands up to any Neve console I've ever worked on... The Power Tube, PowerPre and Q4 eqs 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!"

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!"
Tom Young

Tony Bennett, Frank Sinatra, Lady Gaga

"For 21 years with Tony Bennett, I had been looking for a direct box that translated the nuances, tonality and dynamics of an upright bass. I found it with the Radial PZ-DI. Since using it with Tony Bennett and with Lady Gaga for the taping of their PBS special, to completing 40 shows on tour, it is now the only DI I will use for upright bass."

"The Radial JDI is my first choice for passive DIs because of their transparency and clarity. I depend on Radial products for live and in studio."

"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!"

"Radial Engineering DIs are a staple in the studio as well as my live shows. I am confident in the functionality of their products and that they will always provide me with the desired output."

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."

"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 loses 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."
