The ReedGeek G4 is the newest member of the ReedGeek Universal family. It utilises state of the art, 100% USA alloy with very high vanadium carbide content for exceptionally good wear resistance.

The beautiful “Black Diamond” finish offers a smooth “buttery” glide to the cut. The G4 excels on both natural cane and all synthetic reeds. Exciting features include a newly designed length with a comfortably rounded back scraper (for further adjustment options), a radius tip for precision work and two contoured and curved rail bevels (specially designed to profile rails and re-contour the spine & heart of both single and double reeds). With advanced profiling abilities such as these, the G4 is a must for every serious reed player!
