Neck Stability

[Yank]

Here in New England, bass necks stay fairly stable and rarely need to be adjusted, even with cold winter temps and central heating.
I spent two years in Arizona and with the desert heat and ac in homes, had to adjust constantly. Bass necks were like noodles! Two years in Austin, Tx. was in between. What's it like where you live?

Maybe an 1/8 -1/4 turn once or twice a year.

Very much depends on the bass. I've owned basses that never once needed adjusting & others (especially my Jaydee & my Stingray 5) that were so unstable I spent more time adusting them than playing them.

I think it also depends on your setup. I you go for the lowest possible action, and slight movement could render it unplayable, whereas with a higher action, you may never notice the difference.

I like a low set up. I think here in damp south Yorkshire it seems to depend more on the bass than anything. My MM sub USA seem to like a 1/4 turn every few months but quickly stabilises but the MM Ray Fretless needs adjustment only once every couple of years. I haven't adjusted the neck on my Status in 7 years........

Status necks are great .

I've pretty much always used a Stingray with a Modulus Quantam neck ,that has no truss rod - never touched it. Only required a tune when I changed strings (before I started putting it in a gig bag , rather than the case I got with it)
