Roasted vs Standard necks - Stability?

[drTStingray]

I have Musicman basses with lacquered maple necks, painted maple necks, oil and wax finished maple necks, oil and wax finished roasted maple necks and one with a graphite/phenolic neck!!

 

My main player is a 2018 Stingray Special with the roasted maple neck (it has an ebony board). I have found over the years that all of the basses may need minor adjustment when the weather changes significantly (such as into summer, with higher ambient temperatures) and into winter (where the ambient temperature may fluctuate significantly) especially if, like my Stingray Special, the bass is left out available to play and is out in the centrally heated/non centrally heated home environment, and gets transported to/from gigs quite regularly and is exposed (in a gig bag) to in car temperature and the temperature in a venue/during the gig (where the neck gets exposed to sweaty hands)! 
 

My observation with this main player bass is that the roasted maple neck currently varies very little. It did require a minor truss rod tweak when the weather changed after the summer (to be fair it had a very low action as well). However it doesn’t even go out of tune from one venue to another currently. So I have no problem with the roasted maple neck in this context.

 

I don’t think the other basses I have exhibit different characteristics than this.

 

From my observation, ultra low action will exhibit buzz at the end of the summer/beginning of the winter, requiring a minor tweak of the truss rod (which is, of course a very simple activity on a Musicman). I don’t think there is any difference exhibited between painted, lacquered, oil and wax, or roasted oil and wax necks with Musicman basses - as someone has already said, if the neck’s wooden it will exhibit to some extent the standard effects of temperature/ humidity on wood - AND if you have a very very low action this is likely to become noticeable through minor fret buzz at the start of winter.
