    Hello all. Just picked up a gorgeous partscaster Tele. MJT body, Musikraft neck(22fret, 9.5”), Rutters hardware. The setup wasn’t too great upon arrival - intonation off, action quite high, so I set about correcting things. I got a couple slow 1/4 turns in and the truss rod nut just stopped, so I did too. No further. Only trouble was the neck was still fairly up-bowed, action at slide height, still can’t get the intonation set as a result.

    What does it sound like I’m dealing with here? Broken? Stripped? Normal? I did clamp it into a slight back bow and no market improvements. Btw—This isn’t a blackguard neck with the adjusting but at the heel, this is one you adjust from the headstock with the walnut plug.

    If you loosen the adjustment nut a few turns you can see if there is damage to the surface that the nut presses against, which is not the worst thing in the world to fix, a lot better than a broken truss rod etc. Then as a stopgap you can put a washer ground to the proper size & shape under the adjustment nut and it will pull a bit further before bottoming out, hopefully enough to get the action you want. Good luck!

    Unfortunately the nut isn’t removable on this style neck.

    Did you measure the actual relief? How low are the saddles?

    Got it to .060 at the 12th. Low & high E saddles are close to bottom, not a measurement I took.

    That is an action measurement, right?
    If you fret a string at the first and last frets, what is the string height midway between?

    Whenever I hear about a problem involving the truss rod, I cringe because I know it's probably going to be bad.

    Can you take a picture of the nut?

    Let's see this non-removable nut, please.

    My advice otherwise is always to fully remove it, and apply vaseline liberally to the threads before re-inserting. (Get your minds out of the gutter you guys...)

    We need a relief measurement, the action measurement has nothing to do with the truss rod adjustment.
    I'm assuming the .060 at the 12th fret is action height!
    Saddles close to bottom could be relief or neck angle.
    If you didn't measure the relief, how do you know there is too much?

    Might be worth emailing Musikraft about it to find out if you have a single or double action rod. As of now they only offer a dual action at the head that's hidden, or a bullet that's AFAIK single action. And single action rt double action heel adjust for a total of eight truss rod options. Probably double action.

    You can reset the neck with heat, but that's for another thread after the diagnosis!

    I'd also loosen the strings slack, then loosen the nut until there's no resistance on it, counting the turns. I'm actually not sure how that rod would act in between pulling and pushing for the two actions, but running it through the range without string tension would give you a better idea of what it's doing. Check with a straight edge and note when it becomes straight without string tension, then confirm that the rod will both add back bow and add relief.
    If it starts adding back bow after a turn or two, maybe the neck is fine but the neck angle is off, and the action problem is not relief related.

    We don't know what you know and can't see the guitar, so with no relief measurement in a thread asking about too much relief, we are shooting in the dark. Also of course many non techs feel the nut get tight as it actually starts to move the neck, and think that tight feel is the end of the threads, so stop in fear of stripping.
    We just don't know what's happening with the info provided.

    loosen the nut
    clamp the neck a bit more than you want, so make the backbow a bit bigger, than fasten the trussrod but not to much so the rod would break
    loosen the clamps gently and see if the backbow hold.
    string the guitar and tune it to pitch and wait a while.
    still have to much backbow? gently loosen the trusrod a quarter turn and wait a while.
    if it is not right, do it again and again untill you have the right relief.

    Semantics on my behalf. Indeed, not something I’m currently equipped to handle.

    @telemnemonics has nailed it. Lots of options to check before attempting surgery.

    As it's a partscaster with set-up issues, have the nut slots been filed to a proper depth or is it high at that end of the neck too? Best to sort that before relief if not.

    Upon further inspection the nut slots do appear a little proud to me(especially the D & G which were the most problematic to intonate) and that was my next move. Just sorta panicked when I felt the truss nut stop cooperating a little early on.
