i just got a bass neck to have the right amount of relief by adding a pretty-darn-thick set of washers under the truss rod nut. I was able to turn the nut enough, and I noticed how hard it became to turn at the end. So much tension! Then I remembered the G&L owner's manual saying that the neck needs at least 1/8 turn worth of tension -- far far less than mine required. THEN I remembered that now and then a poster in here remarks that his guitar is crazy-bright and he can't tame it. And I've also read guys say "some necks are just dead." Could these be related to the tension required to get the right relief? Don't you think a neck that's tight as a slingshot will affect tone differently than one that's at just 1/8-turn tension? And is there a way to "tune" your neck in this light, by modifying the business end of the truss rod with washers or creating more or less bow before you engage the nut, to achieve a different tension for the same relief? Or does it not work that way? I.e, if the strings exert x pressure, the neck must exert x tension - equal and opposite? Or even if that's true, can the amount that the truss rod contributes vary and thereby create a less or more "live" neck?
