In Their Own Words

David Wilborn

"The Edwards bass trombone is without a doubt the best trombone I've ever had the pleasure to perform on. This instrument delivers superior tone quality throughout the trombone range, even during awkward interval leaps as well as during moments of extreme dynamic contrast. Since the instrument is designed to be modified, I find that I'm in full control of my sound, and I can manipulate the way my trombone plays. These features are perhaps the reason Edwards trombones are unparallel when compared to its competitors."
