How exactly do you go about swapping out say, a vintage style Truss nut (Screwdriver adjustment), to a newer style Truss nut (Allen adjustment)?
I see you can buy them all seperately so there must be a way to just swap them out right? |

I'd be a good idea to take the original nut to a hardware store or test at home with a couple of machine screws to determine what thread it is so you can be sure your new one has the same threads and will fit. Seems like they have 10-24 and 10-32, but I'm not sure. | So you basically have to loosen the truss rod to it's full extent and then it screws off? How does it not screw off when you provide relief to the truss rod? |

If so, buy a new neck. |

| | Well, thats like your opinion. Man... | | Join Date: Mar 2004 Location: Fife, Scotland | | | The allan adjuster on my MIM jazz is rounded. I was looking for a new neck but if I could somehow get it off and just replace the nut that would be cheaper. Just dont have any spare cash at the mo. Buying a house and all the other stuff that goes with it has kinda left me skint :s
I have tools at work I could use to get the nut to loosen. Just didnt realise this was an option. I have 3 basses all together so I have backups.

I was just curious how it stays on when you JUST provide relief to the truss rod, woulda thought it would just start unscrewing. |

It is basically a large nut and bolt. I think for all practical applications, you don't have to worry about it, you will have enough friction  |

Then adjust until the relief is correct. You don't want to tighten it more than you have to.
The truss rod is permanently embedded in the neck, it has a "bolt head" in the other end. The truss rod never moves, only the nut does. |

All that info works if you're dealing with a compression rod. A lot of companies out there use the new generation dual rods which has a nut welded on the truss rod itself.
In other words when you unscrew the nut, if it removes no problem you've got a compression rod. If it gets to the point that it's pretty stiff as you turn anti-clockwise and gets just plain hard to turn then stop. You've got a dual rod design and putting more pressure on the nut will break it. | | Thread Tools | Search this Thread | | | |
