y violin's f-board has a slight bow, so it dips in the middle (deviates from flat) by perhaps 1/8th inch or less. On a guitar, this would be mostly taken out by tightening the truss rod. Obviously, a violin has no trussrod (maybe they should!)
Also obviously, this isn't super-critical on a violin since the strings are so high off the board, but I'm wondering if this can affect overall action, or (worse) intonation.
Should I have a tech flatten my fingerboard?
It needs to be done right of course, and not all fingerboards are created equal. If your scoop is truly close to 1/8" then it's unnecessarily deep.
Oh, and guitar fingerboards are commonly scooped also, although in that realm it's more often called 'relief'.
Also, using zero relief means the sadlle (bridge) will be higher. This increases the break-angle of the string and gives a guitar more volume & sustain. from what i have read, this may not apply to violins (though there is much debate concerning violin bridge height)
If a guitar's frets are set-up extremely well, and you use 10 gauge strings or thinner, there is really no need for relief. I own about 20 guitars and basses, and they are all set dead-flat.
-Of course, using relief is more common, but mostly because old beliefs are still very prevalent in the industry.
Glad to know that a touch of relief (scoop) is considered correct on a violin. thanks.
Nothing about the string heights and scoop on a violn is calculated to avoid buzzing, which won't happen until the strings are much lower. If there's too little resistance, though, a player tends to play sloppily. Cellos play by slightly different rules, though.
An eighth of an inch is way too much.
-Thanks to you both.
