Hey guys, straight to the point.
If I buy ernie ball 13-56s,will it COMPLETLY stop my neck from bowing if I go in drop d?
Also is there a dramatic difficulty playing change say from 10-46?

Help greatly appreciated.
no, chances are you're going to have to adjust your truss rod no matter what after changing the string gauge (unless you go down to drop C or anything like that but still, for something like that its advised to give your guitar a full setup if you plan on staying in that tuning/guage)

yes there probably will be a huge difference in the way they play.
