Sign in to disble this ad
I have a Fender HWY 1 Jazz (the old one) for about one year right now.
Since I have it, i set it up for about 5-6 times. I had buzz on the last frets, and decided to straighten the neck more. The relief at the 8th fret was about the thickness of a credit card, and I decided to make it smaller. I turned my truss-rod a quarter turn, everything worked great, but within 2-3 weeks my neck started to bend back to it's initial relief, and STOPPED THERE. I did it again, and the same problem...
Any advice?
Can the truss-rod be broken? It works very fine, I don't have to put up effort, and it has effect on the relief, just it goes back...
Is it just because the wood is not dryed out completly and because the bass is relative new?
What should I do?
Thanks a lot, and excuse my english. :P

I could do it

if it makes sense... you know, there's wood surrounding them, so it may take some time to be allright.
I mean, in some cases it could be normal.
and of course, the weather, which was mentioned.
I have to adjust my trussrod back and forth sometimes weekly, sometimes once in a half year because of this.

After several adjustments I lowered my tuning one step down to hear where the buzz is. And now I have buzz on the first frets (1-6) and the last ones (15+). What should I do now?

maybe that would help: http://garywillis.com/pages/bass/bas...tupmanual.html

The quickest way to tell if the right amount of relief is in your neck is to lower the strings.
If after lowering the strings, the notes buzz only above the 12th fret, then there's too much bow in the neck. You'll need to tighten the truss rod.
If after you lower the strings, the notes only buzz in the 1st 5 frets then your neck is too straight. You'll need to loosen the truss rod.
If after you lower the strings, the notes buzz all up and down the neck, the neck's fine. Your strings are just too low.
But I had buzz on BOTH 1-5 and above 12 :|

Measure the relief to see where it's at, and only adjust the truss rod if needed.
If the relief is correct and you are getting buzz on the upper frets, you might simply try raising the bridge saddles a hair. It also raises the question as to whether or not (if a bolt on) there is a shim installed. | I guess this shimming is my problem, but I can't adjust it. I mean, I have no shimming adjustment like on the 70'ies...

To see if there is one in your bass (assuming you are comfortable doing this), you will need to remove the neck. If there is a shim, it will be in the neck pocket. | You mean that I could have a shim without an adjustment hole on the neck plate?
I remember seeing a HWY 1 jazz neck on ebay, and it had something there...

| | Registered User | | Join Date: Nov 2005 Location: Timisoara, Romania | | | After making the neck perfectly straight 2 months ago, it got back to the "starting relief" (but not more) after 3-5 days, and stays there for 1-2 months.
I can't understand this.
Why is it always going back?
I traveled with it, but when it went back to initial relief I had it at constant temeprature / humidity.
Also, I went to rehersals this month a lot, and it didn't moved at al.
Strange...

The SAME problem. I make the neck straight, and it comes back at the SAME relief, and stoppes there. Very strange. I mean, I can fix it once a month, no problem. But WHY?

I'm a tinker guy so I'm always taking my bass apart, for better or for worse.

If the neck needs shimming, the bridge saddles will be all the way down as low as the adjustment screws will go, but the action will still be too high. A shim does no more nor less than bring the saddle adjustments into range.
Buzzing on just the last frets is a bridge height problem if the adjustment screws for saddle height are in their normal range.
No need to make it complicated. Simply turn the saddle height screws clockwise until the buzz clears up. If you have been adjusting the relief to correct a buzzing problem on the highest frets, you have been adjusting the wrong thing, so you may have to correct any mis adjustment that you now have in the relief.
So far as the relief changing, give the neck at least a few months to completely stabilize.
Josh, I completely agree with you about the Willis setup site. I can point out several errors there.
