Whoa, I did think twice about posting the Zachary pic but I thought he might have been onto something because if I remember correctly, what I read said the prs heel was supposed to prevent dead spots high up on the neck and was wondering why he had that scoopy piece when he could've just had major access (if that makes sense!).
Anyways, thanks Setch
As for Zachary guitars, my jury is still mostly out. I think his string tension idea is great and his fretwork looks excellent but there are a few things that even I, not experienced hardly at all, kind of question.
