I have a NS CR5M that has had stock strings for 10 years, time to change! I got a set of NS610 traditionals, with the NS616 B string, and have been currently stringing it up. Here's the problem, top 4 done and got to the B string and it won't fit through the metal washer on the body. Not even close, the wrapped taper on the end of the string won't slip through. I've seem many of you have switched to this set, have you had this problem? Can I just string it through the body without the washer/will that effect the B string sound? Should I drill out the washer bigger? thanks!
