Are Floyd roses good for beginners?
if you spend some time when you first get it, and learn about it, it's actually a very good idea. once you have it in tune it stays that way, you can do some pretty wild whammy stuff, and it doesn't require that you change your picking as some people say.
How do you get a Floyd Rose to stay in tune?
When tuning a Floyd Rose, it is best to have the fine tuners about half way through their range, then tune all the strings using the machine heads. Then give the term bar a good shake, both sharp and flat, and then tune using the machine heads. And then properly tighten your locking nut.
