After living with my 'new' Am standard tele for a week. The tuning sucks. My pink one with some dirty old klusons I won't have to touch for a whole set. I'm wondering wether it's a problem with the cut of the nut or the tuners (staggered type). I get the 'ping' when I'm tuning, when I use a capo I have to completely re-tune. Heavy bending, re tune... So is it the nut or should I stick some trusty Klusons on there?
