checking if trus rod is broken?

[dadodetres]

luckily i never dealt with a broken truss rod....

but if someone is selling me a bass, how can i ckeck if the truss rod is not broken?

[Figjam]

if it was broken the neck would be extremely curved . Just check if the neck is somewhat straight.

That's not truth. It could be poor adjustment. If a trussrod is broken, there should, by all likelyhood, be no pressure on the adjustment nut. Make an adjustment and see if you get pressure.

Hey there,

One of my bass has a trussrod that didn't move at all. I've tried one way and then the other, but nothing to do, not a single movement...
What does it means ?

Thanks

thanks everyone!


so, if relief is good (or semi good) means that the rod is fine?

Not necessarily. I played a Carvin B5 with a broken truss rod and it was playable. The relief was a little out of spec, but not much, and the action was a little high, but playable. Certainly within the range of what some players like. I attribute that to the graphite rods, but I could be wrong.

And Shiveringbass - do you mean that the nut is frozen, or that turning the nut doesn't adjust the neck at all?

The nut is indeed fozen... I'm sure you could try to turn it with your two arms and that would not change, the thing won't move at all...


Thanks fo your help

Does it not move in either direction?

[Shiveringbass]

If my memories are good, I've been able one time to tight the rod but since, nothing.
The bass is a Ibanez ATK 305.

Thanks
