A Jag-stang is a bit heavier then a Mustang imo. But the body feels really comfortable when sitting down with it.
The neck pickup is quiet good, can't say that for the (Santa Ana) humbucker. Altough some people swear they like the stock humbucker, so it's just a matter of opinion. 😉
The neck feels great and even a bit better then my CIJ Mustang, it's truly one of best necks ever made if i say so myself........ 😀
Good luck with it. 😉
