Anyone tried this yet and if so how does it sound. I'm strongly considering one of these new SGJs but I really dislike the 498T. I play alot of downtuned metal and it doesnt have enough oomph for my tastes. Plan on taking the A5 out of the 498 and putting it in the 490. I really like that pickup with an A5. If I could get any opinions on a 498 with an A8 it would save me the time and work and if it sounds bad I can just put them on ebay and go with something I know I already like.
