I've never seen an SG elegant in person, but I always thought it would have a maple top like the SG supremes.
On the SG supremes the top is pretty thick. If I remember correctly its maybe a little less than half the thickness of the body. I'll have to look at my supreme when I get home from work.
Did you ever make it home from work or are you still there?
If you're still there your hours suck!
