I've looked at some measurements and its seems the American professional neck is a tad bit wider at the heel then the pocket of the classic vibe. Anybody done this? I really like the American Deep C and do not like the sticky classic vibe neck. Anybody trying to steer me another way just pass on by please. I like the neck and am buying a CV and adding neck or just getting the 2019 professional. Either you have experience switching necks or not. Thanks in advance.
