ReedGeek Klangbogen Demo 

Saxophonist Rick Keller demonstrates the new ReedGeek Klangbogen !
The Klangbogen™ instantly increases output and depth of tone of the saxophone while stabilizing the extreme ranges of the horn so it speaks with clarity. This allows the player to achieve a rich booming saxophone sound with great forward projection and point (focus) to the sound.
The Klangbogen™, a beautifully crafted brass bow, attaches to the lyre holder supporting the neck tenon-socket region of the instrument, which historically suffers tremendous nodal disturbances. www.reedgeek.com
