Hello all, I've a question about nuts. Yesterday I noticed the top nut on my Yamaha 5 string was cracked (left of the low B string) and in fact loose. This happened a couple of years ago with my Fender Precision (right of the G string). Before I order a new nut I try to glue the loose part back on, which has worked in the past, but just for a while. Getting a replacement is easy, but I have a problem fitting them! I play metal and use fingers. I suspect the aggressive styles pressures the nut to cracking point, or it could be, simply, age. Does anyone else experience what they would describe as a comparatively frequent cracking of nuts? Thanks.
