When I re-tune, am I just supposed to unlock the nut locks? Am I not supposed to even touch the bolts by the bridge? I'm finding very little information on it, and the guy at the music store didnt really help much.

My main problem is the A string. I took off the the nut lock covering the E and A strings, and tuned them with the actual tuners on the headstock. Then, I re-applied the lock. It stayed in tune for all of 15 minutes maybe, before dropping flat again.

Is there a lesson on GT for Floyd Rose bridges for newbies? I can't find one, and I think it would be a good contribution.
