What our artists are saying…


Tony Levin | Radial Engineering Artist


“I’ve already used the new HDI on my bass for a number of recordings, with great results. It’s super clean, and has some dial in options that are wonderful to have on hand. Another home run for Radial”

Tony Levin | Peter Gabriel, King Crimson, Mark Knopfler, John Lennon, Paul Simon




“Radial has done it again! The HDI surpasses all of my expectations for what I’ve been looking for in a Direct Box. It’s so simple to go from ultra clean, with the enhanced Jensen transformer, to a warm and colored sound with everything in between. This is a serious tool for any musician’s tool box.”

Mark Egan | Pat Metheny, Sting, Bill Evans, Joan Osborne, Marianne Faithful





“Loving the HDI. The thing is built like a tank and sounds awesome.
Love dialing in the saturation (color). Makes everything pretty juicy.”

John Rzeznik | Singer, Guitarist, Co-Founder – Goo Goo Dolls

“Sonic transparency is a Radial hallmark. With ‘High Definition’ as part of its name, the HDI abides—it’s designed to be the cleanest Radial direct box to date, but this time around, thanks to its dual topology, the HDI also stands as being the most colorful direct box Radial has ever produced.”
