Correction - "up" bow I just received a 17" SM Martin-style truss rod. The aluminum channel is not straight, but already has some up bow in it - maybe .03"-.05" at the center. The nut is loose. Is this bow normal? Should I try to straighten it before installation? Thanks, Dan |

Is this "up-bow" as defined with the open side of the channel being up? I've never had a problem with one of those, but try this. Put just a little bit of tension on that adjuster................does the bow disappear? If not, send it back |

If not, send it back Nope, it's the closed side of the channel that is bowed up (sorry if I mixed up the terms). I installed it in a rather stiff neck and then levelled the fretboard. All seems fine. Thanks, Dan |
