I've been using a reed clipper for some time now, and really liked the results. (two 2.5 Vandoren reeds have lasted me nearly half a year, and felt pratically the same as when they were new.) The only issue is that the quality of the sound they produce degrades over time (this is the only reason I bought new reeds). I've read the various articles concerning reed shaving and found them all very helpful, but would like to know what specifically to do in order to maintain a "good sound" on an old reed that has been clipped several times. Thanks.
