I like top wrapping, and not everybody does. That's the beauty of this particular forum, we usually make our point once and let the reader make up his/her own mind. Funny, I don't like it on every guitar. But I think it works well with my two SGs so those are the only ones that I do this with. And no, I don't feel that it makes a huge difference. I started doing it in search of additional sustain and as a tonal experiment. I can say that it does no harm, and sounds great to my ear, but I wouldn't try to persuade anyone that it was dramatically better. I like the look of it too... not everyone does. So let us know how it works for you. This topic comes up periodically on this site, so there are multiple threads with lots of Sturm und Drang over it. And also lots of pithy and detail rich commentary by real musicians who play SGs.
