I have a great Tele that is made of old Fender parts other than the pickups (Fralin). I have a huge problem breaking strings with it, right where they cross the saddles. After half a dozen gigs where I break a string after only three songs, I've parked it. In looking at it I see clearly that the strings are tangling with the sharp edges on the height adjusters, which cut in and cause the breaks. Are there any replacement saddles that have a groove or something that hold the strings away from these adjusters?
