I'm wondering about the suitability of walnut as a neck and fretboard material, I may be able to get my hands on some and I'm wondering if I should get enough for a whole guitar or two bodies (quantity is similar, dimensions are not)

It would likely be a neckthru bass build if that influences anything

Well fretboard blanks aren't too bad price wise anyway
