"I have had a lot of junk in my funk, but the "Firefly" DI by Radial is the real funk. She may not sing like a bumble bee or taste like a cherry pie. But the Firefly's bottom end is the best that money can buy."

"When my sound engineer changed the front end of my vocal channel to the Radial PowerTube preamp, Q4 EQ and Komit compressor, I stopped mid song and asked why we did not do this sooner? My vocal has never sounded better!"
