Hello everyone A warped spot around 7th fret is causing my Jazz bass to buzz heavily on the first few frets. At first I thought it was due to the age of the instrument (1989) but then I took it to a local luthier in Exeter where the guy told me it was the Knot (or grain patterns that looked like there was a branch coming out) which is a weak-point in the neck's construction. It's a 1989 Custom Shop 60's Jazz Bass. Does this happen often? I have never seen these type of patterns on a maple neck before, certainly not on a high-end instrument. And if is this is a Fender quality problem, will they repair or replace the neck if I'm not the original buyer? I don't want to spend an arm and a leg to buy a replacement neck... Thank you for your time.
