Hey guys,    I have searched the forums for this topic and haven't found anything.  So I want to play some of the amazing metal customs that you've all worked so hard to create. However, some songs require a very low tuning (B standard) like Amon Amarth , (B drop A) like Slipknot for instance.   I would like to put some heavy gauge strings on my guitar.  I have another guitar I'm willing to do this with. My question is, do I have to raise the action on this guitar to tune so low, even with hea
