Weather change in London - all my basse's neck mooved...

[harald_rost]

Some observations from Germany (Bavaria).
I don't think we have very extreme weather and humidity at all. But I try to keep it in the range of 40% to 70% in the house.  
I have a 1966 Fender Precision. His neck do not moving since 20 years. I have it since 1978. Amazing. Even I have to tune it once every three months. Solid as a rock!
My 1976 Series 1, which I have since 1999 seems to be equally. Also my two Warwick Thumbs, which are 1987 and 1990 models. I think older basses tend to be more stable.
Totally other is my Chapman Stick, which I have to adjust at least twice a year. But this is a very sensible instrument an the tapping technique need a very flat fretboard.

Chiming in from The Real Northern CA Chico here.   Every October I have to readjust the trussrod on my Essence 5 like clockwork.   I know a change in the weather is coming then.   I have gotten used to it and plan ahead for this time of year. No big deal with how easy the crew has made it to adjust. Brilliant design!

I just gave my fretted Rogue its autumn truss rod loosening, haven't gotten to the fretless yet because I'm not playing it as much at the moment (and what's a little extra mwah between friends anyway?).  That's the pattern here in beautiful downtown Cotati(conveniently located just 5 miles from the Muthaship)--loosen them every October, tighten them back up around May.  Tuning is pretty stable on both, but when I play outdoors (which I've been doing a lot lately) I'll generally go up a few cents on most of the strings as the temperature drops.  Don't notice a big difference between the walnut pinstripes in the fretted neck and the purpleheart lams in the fretless in the truss rod and tuning departments.  The tone department--now there's another matter entirely...
