Most of you guys use 10's on your SG? Are there significant tonal differences to heavier strings on an SG and dropping down from standard tuning? I'm fairly new to guitar playing. Why do guitarists tune down 1/2 step anyway; assuming tuning down means all 6 strings are dropped 1/2 step? Why not keep standard tuning and just drop your starting point 1 fret; same thing isn't it? Does tuning down 1/2 step make bending notes that much easier? I've read about matching the vocal range reasoning, but again keeping standard tuning and dropping your starting point to a lower key achieves the same thing doesn't it?
