Based on what I can deduce, that is a rather dramatic twist. As it is a rosewood board, there is hope. What I'm about to say is the oversimplified procedure:

The neck can be clamped on a neck heater. The truss rod would have to be readjusted under this pressure for best results. Strategic placement of the clamps will forcibly straighten the twist while simultaneously heating up the neck/fingerboard allows the glue joint between the neck and the fingerboard to slip. This will reposition the board so that once the neck is allowed to cool down, the joint will reharden where the neck won't be twisted and the board will be level. Both the board and the glue along with the truss rod will now aid in resisting the neck's proclivity to twist. The problem shouldn't come back.

Setting the guitar up with some crazy, unrealistic string set and/or action or wetting the neck under pressure or leaving it under pressure in the back window of one's car exposed to heat just won't do. Don't forget, the neck's finish is involved here too.

This is an outright professional job where as has been said, the price is comparable to or exceeding that of some replacement necks.

Hi, long time no seen!

Actually everything turned alright in the end. I took the guitar to qualified luthier, almost year ago. He inspected it for a while and ended up saying that this type of curvation is just good for a guitar neck. Neck is more convex in the area of bass strings, that need more space to vibrate, and more flat under treble string. After slight adjustment the guitar was better than a new.

For those of you who are interested in reason why this problem occured at the first place: according to luthier I speaked with, the grinding on the lower part of the neck was done incorrectly. You could see bare eyed from the back of the neck that more wood was grounded from the treble side of the neck compared to bass side.

In my first posts last year I forgot to mention how little this affected playability of the guitar. The only noticeable result was slight buzzing. However I discovered later that main source of buzzing wasnt the neck, but frets. There was a few frets that were slightly elevated, and after lowering them the buzz was gone.

So, my Fender is alive and well. Sorry for not posting this earlier, I just forgot . I think this topic can be locked now.
