Testimonials

The ADL 700 preamp is incredibly versatile,” he adds. “It’s got EQ, compression, and it helps shape the sound so I don’t have to do it after the fact. It just sounds better. It’s got that little tiny edge that I would get when I go into a studio and run through some exotic handmade British console.
Steve Morse | Acclaimed Guitarist Deep Purple, Dixie Dregs
