Truss rod acting up

Sign in to disble this ad
About a week ago my bass started having some very bad string rattle. I took it to the shop that previously set it up (they set it up about a month ago, played fine).

They said the truss rod could have slipped, as the neck was a little to straight. They adjusted the truss rod and it played fine.

When I got it home the rattle was back. The neck looks a lot straighter than it did when it didn't rattle. I raised the action of the E string, the only string that buzzes. Now it's a lot higher than the others, but any lower and the buzz is unbelievable.

Also the E string side of the neck doesn't seem to have as much bend as the G string side, maybe my imagination.

The shop gave me an allen wrench they cut off to fit the socket to adjust the truss rod. How can I fix this.

Thanks

First off, you didn't specifically mention adjusting bridge saddles. You shouldn't be using the truss-rod to adjust string height (just in case & for others new to this).

Straightening the neck adds tension, so 'slipping' would cause more relief. But you also mention different bends for strings. By this do you mean the each side has a different amount of relief?
It may mean a warped neck. One thing to rule out first is to see if it is sitting in the neck pocket properly (bolt on I assume?). Make sure the pocket is clean & level. You might have a case where your neck is shimmed on one side.
After that try looking at the nut. Is the groove noticeably deeper relative to the others?
You might also be experiencing high frets. Frets CAN work loose and it won't take more than a hair width to cause problems.
If all that fails. loosen the rod to add a bit more relief than you are used to and keep a close eye on what it is doing on BOTH sides of the neck. If the neck straightens evenly, you may get lucky by 'training' the neck back. If it straightens at different rates (on ether side)... that's beyond me.

Hope this helps.

Thanks. I'm new anything concerning the truss rod. I've been playing this bass for about 4 years now (played for about 7 years in total), this is the first time it's given me problems.
