Re: Which Seth is hotter?
I've got the A2 50th Anniversaries, and they sound great to me.   I think they're only a tiny bit hotter than regular Seths.....hard to notice when the numbers are that close.
If you want hotter, order a lightly potted Brobucker from the Custom Shop, and maybe a Pearly Gates neck in nickel.   I think I know what you're after, and that's it.
