I've used 3 saddle brass bridges forever on Telecasters, both Fender reissue originals and various third parties. Presently, my beloved old 52RI has some brass Callahan "crooked" saddles that intonate very well and sound great. With all of these, I've had the problem of the high E and sometimes the B digging grooves into the brass over time, resulting in a "sitar" like buzz that is no good. Every few months I have to sand the offending saddle with very fine sandpiper to get the grooves out, and tone is restored. I use .009s or .010s, the issue remains the same. I haven't seen this problem mentioned on any posts that I can find, and so I'm curious if others encounter this issue. Is there any advice beyond what I've been doing?
