the JB2 is one of my favorites - - in mahogany though there's a chance the low end will be too mushy for you. But I'd try it anyway - it sounds really cool.
I have an Alan Holdsworth model pickup which I contacted SD about.
They said it is a JB with 2 sets of screws and no slugs. I have it in my Kramer (alder body) and it has a bit of a spongey bottom end, but I actually like it, and would love it if this guitar sounded like my Kramer. So, a #II magnet sounds like it will help me a lot.
Anybody know where I can get one?
