So i just got a new Schecter Omen Elite 6 for Christmas, and i tried tuning to D# to learn some Alice in Chains songs and ill get each string to perfect tune then about 30 seconds later if i play the string again its out of tune like almost a half step... i have a floyd rose and its still slipping out of tune even with the tuning nuts. Can anyone help me figure out how to fix this? Is this something i can fix on my own or should i take it to Guitar Center to have it checked out?
