    Hi I'm new to the forum. I just bought a new in the box Ibanez 305E 5-string bass on line, and I need to adjust it because all of the strings at the first fret buzz badly. I tried to adjust it at the bridge, but that didn't change it enough to stop it and it throws the fret gap off.

    I noticed that when I push the neck away from my body the buzzing stops so I think the truss rod needs a tweak. So I have a question.

    Which way do I turn the wrench, and how far? It doesn't need much, as I can stop the buzzing with a slight push forward with my left hand at the back of the neck.

    Also pulling the neck backward towards me (if I was standing up playing the bass) causes the buzz to get worse, if that helps with the direction I need to adjust it.

    Also for those that might want to know, the truss rod for this guitar requires a 5/32nd Allen Wrench.

    Thank you!!

    Sounds like the neck might be too flat, needs more relief. You should loosen the truss rod nut, 1/4 turn counter-clockwise then give it a day to settle before rechecking and making any further adjustments.

    Needing to wait a day is a myth. A few minutes will suffice.

    Thanks for the quick feed back! Since the strings are all loose in order to adjust the rod I didn't want to have to keep loosening and tightening them.

    This is a brand new guitar, so I don't know how that might affect the potential settling issue, if it is one. I don't know that much about it honestly.

  6. If it's an Ibanez the truss rod is probably 4mm. 5/32 is close but if you have to torque it very much you're liable to round off the wrench or round out the nut.

    Yes I did see the basic set up questions, but the truss rod video was for Fender so I thought maybe it wouldn't apply to Ibanez.

    Thanks for the heads up on the Metric for the truss rod. I don't think I'll have to tweak it much, but I will certainly be careful since all I have are the standard allen wrenches. Plus I'm loosening it, so that's in my favor too.

    Update: That quarter turn did the trick, no more buzzing! Thanks again.

    That's a 4mm wrench, Ibanez uses metric everything. 5/32" is like 3.9688 mm, which is close, but any strong torque could round out the TR nut.

    glad you got it fixed..

    -you can turn a truss rod with the strings tensioned.
    -if you have problems with which direction to turn, use a tuner. back bow raises the pitch, forward bow lowers it.
    -new ibanezs' come with a bag of goodies. a pair of allen wrenches is included. as well as a pretty informative booklet.
