A Fix For Truss Rod Rattle

    For those of you that have had troubles with truss rod rattle, I'd like to share with you a product that really does work.

    First of all, determine that the rattle is indeed your truss rod, and then make sure that it's not simply a case one that's never been tightened. On my bass, the rod was tight, yet you could hear the rod rattle in the neck when the open E & B strings were played, or if you rapped the back of the neck with your knuckles. I had eliminated all other possible sources of the rattle, and so had my guitar tech.

    I'd had this problem years ago with another instrument. I sent it back to the builder, who poured a rubber cement down the truss rod canal to silence the problem. He then sent it back to me. To my horror, when I opened the case, there was brown ooze flowing out of the truss rod canal...it hadn't dried yet! Anyway, once that mess was cleaned up and the glue was dry, the truss rod was all but frozen in place. So this fix was one I didn't want to use except as a last resort. I've also heard of "tool handle plastic" being thinned and poured down the canal in the same way.

    Frustrated, I searched around the net, and I found this fix on a repair forum online. With nothing to lose, I gave it a shot. The product is called "Chair-Loc Plus". The idea of the product is to fix chairs without gluing by swelling the wood in the joints. It works within 30 minutes. It comes in a 3-oz bottle with a syringe and two needles. About 9 bucks.

    Heres' one source, but there are many online:

    Anyway, I put the bass on the stand, took off the truss rod cover, and injected some of the Chair-Loc down the truss rod canal. 15 minutes later, no more rattle, even with the hardest rapping on the back of the neck. Woo Hoo!!!

    I hope this helps some of you that have had the same problem.

    Thanks Chris, though I really can't take credit for inventing it...just for searching various repair forums on the net. I'm still stunned at how well it worked. Heck, maybe it's time to try it on some chairs!

    how about if you can only access the truss rod from the body side?

    You break off the headstock....









    Wouldn't you just hold the bass upside down?

    I'm assuming it does some nasty stuff to the wood and I personally would never use it on my bass, but each to their own...

    The stuff is pretty thin and runny, but that's a long way to go unless you had a pretty huge syringe.

    As far as it's effect on the wood, I didn't notice any negative effect on the tone.

    In my opinion, a bass with a truss rattle that can't be fixed is headed for the garbage bin anyway, so it didn't seem like much of a gamble to try the Chair-Loc.

    Having said all of that, proceed at your own risk with the product. It might be a good idea fix a chair with it first to get familiar with it's properties.
