Hey, I have bought a nice pre-gibson Tobias Sig., but I don't like the action, and so I want to make a new setup. The first problem is that the owner didn't had the tools for the trussrod. The second problem is, that I have never fiddled around with such a double trussrod system. Could somebody who owns a pre-gib. Tobias please explain me, which tool I should use and whether I have to consider anything speacial when doing the setup. thx.
