Big heads are awesome. I much prefer them to the small ones. They just look cool. Plus that little bit extra wood up there improves the tone of course
Btw, I do own a Fender '69 relic and the neck is very similar to my real '66 below. U shape and chunky round. No finish left on this neck. BTW, why can't Fender get their pickguards right on all their relics?!
