I was thinking of getting a Floyd Rose guitar for some of the songs I like to play that use dive bombs in the solos and such (Avenged Sevenfold being a prime example), but I want to be able to tune to Drop D without using a Tremol-No or a D-Tuna (as I want to be able to still use the tremolo both ways). I've been researching it a bit, but I can't find a straight answer on how to do it - Some people say that I can do it with the fine tuners alone, while others say I can just undo the locking nut, tune down, screw the locking nut, and fine tune, while OTHERS say that I'll have to change the spring tension once it's tuned. So basically, I just want a straight answer on kinda how to do it, or if I should just take it to a shop to get it done. Thanks in advance!
