Re: [Harp-L] re: Breaking-in
The material of the SS reeds is likely to be more fatigue resistant than copper alloys. However, unless I see evidence to the contrary, I conclude that any new SS reed is as strong as it is ever going to be and a brief period of gentle playing won't increase its fatigue resistance. A period of gentle playing might get you into the habit of playing gently, thus causing your reeds to last longer.
