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 heavy gauge strings? What gauge would you use? What advice can you give? Thank you so much!
