Thanks Ted! good luck on that, sure will work out fine, got a lot of responce on that, lots of builders say they use them ,metal or steel is i think the best option, but then use new hhs drills for good and clean holes.i use copper on the 3 string that will take the pull, but for 4 or more use steel or galvenized metal, and thanks for the nice compliment on the slide tune! Thanks ! Greeettsszzz to ye! A.D.
