Adrian Bellue

"Whether I’m performing live or recording in the studio, there's no parallel with the consistency and control of the PZ-Pre. I can get the sound I want every time and never sacrifice my tone or dynamics. Everything I need is contained in this preamp, and it's bullet proof to boot."
Al Petteway

Renowned Grammy-winning fingerstyle acoustic guitarist

"I'm blown away. The Radial PZ-Pre is like the holy grail of acoustic guitar preamps. We use them on five very different acoustic instruments and all of them sound completely natural. The PZ-Pre gives us the best amplified sound we've ever gotten."
Andrew Osenga

Steven Curtis Chapman

"The first time a venue provided me with a Radial JDI I noticed an immediate difference in clarity, presence and fullness. I went and bought my own the next day.

"I added a pair of Radial J48 Stereo DIs to my acoustic pedal board for the tour this year, and I must say they are amazing. Transparent, punchy, and downright musical in processing my signal. My only regret is that I didn’t add them years ago to my rig. Thanks Radial for making such world-class products."
Calum Graham

David Morgan / James Taylor

Engineer - James Taylor, Paul Simon, Stevie Nicks, Bette Midler

"The Radial PZ-Pre is hands down way ahead of its competitors! The tone and versatility is amazing. The boost section is perfect for solos and the parametric midrange helps dial in the best tone possible. It's truly a masterpiece! The most useful tool for amplifying an acoustic instrument I know of. The frustration is over! "
Ewan Dobson

"The Radial PZ-Pre is the glaze on the ham of my sound. Thanks Radial!"

"Before I got the Radial PZ-Pre, the sound quality of my acoustic guitar would always vary from venue to venue. The PZ-Pre allows me to dial-in my acoustic once, and bring those settings with me wherever I go. No matter where we are, my guitar sounds great. That's why I'll never do a show without it."
Jeff Troxel

National Flatpicking Champion

"The Radial PZ-Pre is in a league of its own. It's the most natural-sounding pre I've found. It's amazing how versatile this unit is. I'm using it for my nylon-string, steel-string flattop, and even my archtop jazz guitar. Thanks Radial - you hit a home run with this one"
Jerry Douglas

Alison Krauss and Union Station

"I am really happy with my J48s. I replaced all my old direct boxes and found the J48s to have more output and less coloration. My music has never sounded so good!"

"The Firefly gives you a choice of warm tones that help the whole recording process. I love the adjustable gain for low level guitars without the noise. Thanks Radial for another piece of great gear!"
Jim Kelly

Australian jazz guitarist, composer and educator - 'The guitarist's guitarist'

"In 2008 I was on the verge of giving up trying to amplify my Australian acoustic made instruments for live gigging. By chance, I read that James Taylor was using a Tonebone PZ-Pre so I figured that this preamp might be the solution to my problems. Boy was I right. This preamp solved every one of the problems for my nylon-string, steel-string and mandocello. I couldn't possibly conceive of doing a gig without it."
Jimmy Messina

Guitarist/songwriter/producer - Loggins & Messina, Poco, Buffalo Springfield

"As a utility player, the 4-Play by Radial has made my life way easier. This 1 input, 4 separate DI output device now consolidates my mandolin/dobro/acoustic/banjo into one clean, compact, great sounding box. Our FOH guy, my tech and I are much happier. Thanks Radial"
Josh Turner

'Smokin' Joe Robinson

"As soon as I tried the Radial PZ-Pre, I was amazed at how warm and musical it sounded. It was clean and present, but not bright. I love the EQ, the mute function and the multiple outputs... all from one pedal! The PZ-Pre delivers my guitar sound like a pickup should."
Kenny "Babyface" Edmonds

Grammy Award Winner

"When it comes to switchers for Protools playback , bass DIs and acoustic DIs, Radial is always our first choice. No matter where we are in the world, they are a 'must have' on every live concert we do. Radial always give us a pure, warm unforgettable sound. Thank you Radial for making real audio gear that is built to last no matter how far or wherever we travel around the world."
Kerry Marx

Grand Ole Opre

"The PZ Pre is the perfect centerpiece for my acoustic rig. My tuner's always on, reverb is in the fx loop and footswitchable on or off, and I can switch between 2 guitars, each with its own level control. The mute is totally silent; I sometimes tune during accapella sections and if there were any noise it wouldn't be cool. So, full-featured and sounds GREAT!"
Kevin Blake Goodwin

Winner - 2015 Canadian Fingerstyle Guitar Championship

"The Tonebone PZ-Pre has everything I need in one single unit. I knew the moment I saw and heard the PZ-Pre I had to have it. It provides the most natural sound for all my acoustics; it's a musician's dream. On stage I can have another guitar ready to go, without having to switch cables. I really wish I would have found this sooner! This has made all of the difference in my performances. Radial Engineering did an amazing job designing this unique device!"
Laurence Juber

Grammy award winner, Wings lead guitarist

Marty Stuart

"The Radial PZDI seems at first glance like a very simple DI, but by engaging the low pass/high pass filters and adjusting the 3 position impedance selector I can get a rich tone in a matter of seconds. Getting a great tone shouldn't be complicated if you have great gear and the PZDI is proof of that."

Steve Stevens

"As always Radial has done it again. The JDV is a direct box on steroids. Whether I am recording a DI guitar or the high output of an active bass guitar, nothing gets it done as well as my JDV. A totally transparent signal with just the right amount of air... I have grown to trust Radial products like no other company I know"
Steven Bennett

Acoustic musician - 6-string and Harp Guitarist extraordinaire

"I have never had a richer, more present sound onstage than when using the Radial PZ-Pre. My signature 6-string sounded fantastic and my harp guitar was spectacular. I am absolutely delighted with my sound now. Thanks, Radial."
Taylor Goldsmith

Singer, guitarist - Dawes

"We’ve tried countless DIs with my acoustic guitars and nothing compares to the J48 by Radial. Not even the fanciest boutique tube DIs out there."
Tim O'Brien

Acoustic Guitar & Banjo - Mark Knopfler, Alison Krauss, Steve Earl, Garth Brooks, Dwight Yoakam

"I use the PZ-DI for guitar or banjo and while it has no EQ, it's very friendly to those instruments. The guitar pickup is a K and K and it works best using the PZ-DI flat, although sometimes it helps to dial the low end down a bit. For the banjo, I tend to push the high end roll off button, but basically that box is just clean and fat and the sound guys have lots of good round signal to tweak."
Tommy Emmanuel

Grammy-nominated 'Certified Guitar Player'

"I love my Radial J48 direct boxes! They produce a big, fat and clean signal that is so good; they are the ones I use for my live recordings. Thank you Radial!"
Tyler Sellers

FretMonkey Records artist

"So many times I've played a concert and the sound just wasn't there. Once I started using the PZ-Pre, It gave a whole lot more control on how I wanted my sound to be. I love this pre-amp and I'm never going back!"
Zac Brown

Grammy winner - Zac Brown band

"The Radial PZ-Pre is the most natural sounding acoustic preamp we have ever used, not to mention its road-tested durability. Thanks Radial."
