So i got a synyster gates custom. It rocks. But the problem is i have no idea how to tune it. It has the floyd rose tremelo and that stuff and i can't tune it. This is a problem because i play a lot of songs in drop d and drop c, so i need help!

Can someone give me a (detailed would be nice) guide to tuning this guitar!

Thank you.
