Hi, I've looked throuhg the forum already and can't find the answer to this !! I have a Conklin Groove Tools 7 string and a Yamaha TRB II 6 string and understand the basics of setup but do not consider myself an expert by any means !! I'm comfortable with the idea and adjustment of truss rods, but what if you have 2 truss rods in 1 neck...? Do you adjust each one individually or turn them the same amount at the same time ? Are they treated seperately or as a pair ?? Luckily the basses don't need adjusting, but it's always something that I've wondered ...Any help would be appreciated !! Cheers....!!!
