i've been getting really pissed off because im trying to work harmonics on my new rgr420ex, but whenever i use the whammy bar it creaks up at the top and sets off the other strings, makeing a loud highpitched horrid sound, it goes away when i loosen the string locks at the top, it does it when theyre tightened, up and down, plz help
come on people, need help with this
That sounds like the strings are slipping through the locks at the top. It might be a problem with the guitar itself, or you must just be a wuss and not tightening them enough. Try tightening them and seeing if that stops the grinding.
when tighten them they make a weird creaking sound, so i dont tighten them as hard as they go cuz im worried that it'll damage them, but i'll try it
You should be able to tell when you're tightening them too much, because they'll pretty much stop moving and you'll be straining to get another quarter turn.
