    I have a SG with a blocked tussrod... then I decided to look the inside details. Watch out!

    Holy Moly, looks like someone used an impact wrench on that!

    Sure makes one wonder the thought process, or lack of it.

    Nice job opening it up.

    Seen that happen with a car's axle and too much torque. Didn't know it was possible with a truss rod. That takes a special kind of skill.

    And while Mr. Banner got more and more angry about the quality of his Gibson guitar he turned into The incredible Hulk...

    ... uh ... really?

    Ouch.

    Don't get how that happens - that must have been feelable long before it went that far...

    Don't know what happened exactly, I bought it cheap (probably because of that ... undisclosed issue) :-/

    To me, they welded the nut to the bar which is the kind of "thing that should haven't been"...

    Amazing what can be found when one looks under the hood!

    Are you thinking of replacing the truss rod, or are you done with this guitar?

    They ... welded ... the ... nut ....

    There’s a stream behind my house. When I first bought the place 25 years or so ago, there was a submerged boat trailer in the stream. I pulled it out, no small feat from a wooded bank 6 feet or so above the water. Then I discovered why it had probably been abandoned: some mental giant had welded the wheel rims to the hubs. I guess they thought the tires would last forever ....

    Surely this is some kind of twisted luthier prank?
    How would you weld the nut inside the channel unless doing so before installing?
    How would you twist the metal bar over the rod without the fretboard cracking open like a fully hatched egg?

    I don't know, of course, but I wonder if they welded the nut because they had the neck 'perfect' and didn't want to have it move from its perfect adjustment...

    I mean, that could be it, yes?

    The adjustment doesn’t move on its own. The tension on the trussrod provides plenty of pressure against the nut to keep it from moving. However, wood DOES move. There is no good reason to prevent the nut from turning when needed.

    I don't know but perhaps they've been too fast welding the control bar which has a ring to push the nut and bow. I think when they soldered this ring they also touch the nut by mistake (and didn't quality control the tussrod)

    I wrote this the other day but deleted it, but it’s still bugging me.
    If it was overtightened woukdn’t the channel have twisted clockwise?
    Slackening would not twist the channel!
    What kind of anti laws of mechanical physics is this!!!
    Am i missing something or what?
