 "David Enke is probably the most innovative builder I have ever had the pleasure of knowing. This man is taking stringed instruments to a WHOLE other level. Check out his page. Some of the things he is doing are simply unheard of in music. It's my belief that he may be one of the greatest innovators in musical instruments since Leo Fender, Les Paul etc. All built by one guy. New pickup designs are absolutely insane as well." - Bass Porn
