Fiber Onyx Soft reed. Guys, I just sanded my soft reed tip. Used 1000 grit wet and dry sand paper. I put the reed on a mouth piece out from the tip just a little bit. Did it dry. easy to do! Slowly. Sanded at 90 degrees like the Hartman site teaches. Bottom line,,, the reed plays much better. I was having trouble with the high notes. No problem. I sanded 3 times, trying to play as I went. Good luck! Take your time. Tim
