Ok I ahve my Ibanez s470 which has a floating trem and a locking nut. I am quite new to floating bridges by the way. I just changed the strings on it to the same guage as it was. I cannot keep it in tune for a second. It has been a good month or so since i put the stings on and havent been able to keep the guitar in tune the whole time. I unlock the nut tune it lock it againg fine tune it, by the time i get back the the lowest e string again its out of tune. Im considering selling the whole thing its got me all upset now. lol but any tips will help.
