Fingerboard top surface scooping.

Could you explain why the fingerboard becomes convex as the humidity increases?

Because due to moisture absorption the free part of the fingerboard goes down, the opposite happens when the environment becomes dry (this is an effect that takes a few days, it is not immediate). The fingerboard will become convex (or if you prefer, a bump would form at the end of the neck, which is about halfway up the fingerboard) if it were perfectly straight at the start, if it were with a scoop it would flatten without becoming convex, hopefully. It depends on the starting conditions. On thin fingerboards these movements are usually more noticeable.

You can verify this with a simple "scientific" (:)) test, try to wet the fingerboard surface and see what happens.

I believe that what works for classical violin players should work for electric players , since most of them are classically trained. Maybe there's a distinction with fiddlers which prefer less scoop in general from what I understood. Thank you for your dimensions. very insightful. 

It is true that different players have different preferences, but I thought that maybe there's some scoop dimensions that would provide an optimal fingerboard for most players, leaving the customized solution for specific cases.

A fingerboard (or a violin) that is good for everyone I think is the dream of every maker:).

In my opinion, a fingerboard with a slightly differentiated scoop  is the most universal, but we are always in the field of preferences and opinions and I think it is impossible to get out.

Thank you for your insight on this topic! very helpful. 

Yes I think that it is difficult to find a universal fit and it's a matter of preferences otherwise we would have seen a supermajority in the study MJ performed :lol:,

Interesting though I have met some pretty advanced and exceptional violinists who were literally "magicians", they could perform so well on literally any generally properly set up instrument without having any playability issue.

Yep, this is one of the problems in establishing a standard.:)

Thank you for this Marty, we have an old fiddle with a warped / twisted neck, I always wondered why it didn't seem to cause any problems with playability... perhaps this is one reason it is so nice to play!

Great photo!  thanks

It shows the level bridge and level end of the fingerboard much better than my photo.  

I wonder what's the best amount of twist.

Maybe what you are looking for is "catenoid" if your CAD system can create that shape. A section out of one is actually the ideal shape for a fingerboard.  Here's what one looks like.  This one is way to fat.  Imagine stretching this shape out very tall so the top is the radius at the nut, and bottom is radius at bridge...  It would be almost a cone. Almost. A cone with a little bit of a waste.  Then chop a section out of it, and wala.
