I bought a '77 Bird from George (our very own Old Man C) that has a bit of a twist in the neck (he told me beforehand of course!) maybe from having it's headstock broken. Anyway the neck does seem to have a slight twist to it, but its much maligned ( by some folks, not me) 3 point bridge more than compensates for it - in fact it's an excellent player, often go-to bass that sounds great. Thanks George!
