so i have a fender HSS strat and i've just changed the string and im still having tuning problems. the problem isn't that the guitar doesnt stay in tune, but whenever i use the whammy bar even a little, it comes out of tune. most of the strings stay relatively in tune, but the g string always goes like a half-step sharp. all the strings are strung correctly, and im using diaddiario 9s. Help is appreciated

It's probably the nut. You'll have to take it to a tech for them to have to looked at, and if it is the nut, they'll have to widen the slots, or they may just replace the nut.
