Bought as a replacement for a bad Otto Link STM ligature, but now using on a Dave Guardala Crescent.
Brilliant ligature. I was sceptical about reviews on its 'openness of sound', but I must say, it does make the whole set up feel more free blowing and 'open'. It does seem to enhance approaching the bottom end at pp or subtone, and as strange as it may seem, it does seem to warm or round the sound up a bit!
Highly recommend!
