Made a saddle for a customer about a month ago. First time I ever used Corian; I usually use bone, micarta, or tusq. A week ago he stops me at church with a broken G string. This is one reason I made him a new saddle in the first place. Upon inspection, he already wore a pretty deep 'seat' into the saddle. This is why he was breaking strings already; he's a hard strummer. I sanded out the nicks, and I've asked him to ease up on the strumming but, has anyone else experienced this with Corian? My saddles usually are good for a year before we have string break problems due to wear. Break angle, etc are fine.
