I found a CV-2C in a local guitar shop that plays great and appears to be in nice shape other than the neck. There is a slight gap between the fretboard and body on the upper side. It looks like the neck has shifted a little because there is some finish cracking on the heel. I'm wondering if the neck twisted or is this a minor repair? I've tried to attach photos but apparently I don't know what I'm doing.... Any suggestions/tips on how to attach photos from my desktop? And opinions on whether to buy or not with the neck issue.
