unless Warmoth is rolling something out in the near future (or I've simply missed their offering this), you won't find a 24-fret J-bass neck here to match this body configuration
from what I can see in this image, it appears Fender shifted the bridge inwards to accommodate the added fretboard length. I guess it saves $$$ from redesigning the entire lower cutaway to accommodate the neck with a traditional bridge location
all the best,
The thought of a "regular" Jazz bass with an extended cutaway for 24 frets makes me horny as hell, but if you extended the cutaway, it would change the shape of the bass too much and it would not look right.
Like you said, they made the neck longer and shifted the bridge up to compensate. This sounds like the best solution to me, as the bridge location is a very unobtrusive change.
I doubt that it has anything to do with pinching pennies, though is is quite a cost effective solution.
The only problem with necks like this is that personally, when i play a 24 fret neck, i get lost on the upper frets near the heel, because i am expecting them to be lower down.
I guess this is just a matter of adjusting your technique.
In either case though, unfortunately you are out of luck as far a Warmoth neck goes. :sad1:
