S shaped Fender neck

[4 Strings]

I have noticed on several Fender basses (perhaps any bolt-on neck type) that they go buzzy up the dusty end. It appears that while the rest of the neck can be set to an ideal relief with the truss rod the body end seems to bow upwards for a few frets causing buzzing.

Slackening the truss rod seems to let things go further down the fret board but its as if the area bolted to the body holds itself rigid despite the truss rod and so the neck becomes very slightly 'S' shaped.

Anyone else found this? Any ideas for a solution?

the frets above 15 are only for decoration, it's no surprise they don't work properly

Shim the front of the neck pocket to raise the neck joint angle - then tweak the truss rod to suit...

Thanks, not an unusual fault then, not easily remedied either. On one, my ol' banger, seems to have 'popped' recently. Its already got a shim - how many Fenders don't - and no amount of fiddling with truss rod etc can straighten it. Its not too bad, not sure its going to be worth the cost of a luthier's attention.
