Right now I am playing on an Ibanez RG-570. It of course came equiped with the Floyed Rose Edge Trem. I've been around free float trems for a while. A lot of people think that the best way to accomidate lower tuning you have to adjust your springs. (Which is not true) The standard gauge for the Floyed Rose is set for Extra light gauge 9's And if you put reg light gauge 10's all you have to do is drop all your strings down a whole step D tuning and you'd have the same action you did with the 9's at standard E tuning. But even so my problem is that I don't have much expierence drop tuning. My guitar has the Wizard styleII neck and I was wondering if anyone out there can tell me the best route to go with heavier gauge strings without having to worry about the neck on my guitar getting warped.... Please any help would be great.
