I got a LP Custom I keep in D or drop-C that I've a couple of pickups in lately so I'll throw my $.02 out there. If the JB ends up in the ballpark, but isn't quite there the MCP Black Iron is worth a look for sure. It's in the same camp. It's supposedly a lot like his Angel Dust, but with an A2 magnet. Apparently the A2 gives a rawer sound than the A5. I only have the Black Iron so I can't comment on that. Anyway, it's nice & tight with plenty of drive, but it's not ultra high output. It's just thick enough in the lows & low mids, but it has no mud. The high mids have a strong, driving, aggressive character to them as well. It cuts like a knife too.
If the JB isn't in the ballpark then there's the MCP Nasty Nasty. Wade described it to me as being like a hotter, tighter, more aggressive Detroiter. Way different than the Black Iron, but killer as well. Feels a little tighter with a bit less output than the Black Iron, but not much either way. It's not quite as modern sounding & more balanced in the eq than the Black Iron. The Nasty seems to mold itself to the guitar more cause there are no eq protrusions. That said, in the same LP the lows & low mids aren't as thick & chunky and it's not quite as cutting in the top end as the Black Iron. Still plenty of highs to cut, just a little sweeter. The mid mids really shine with this pickup. Overall character is open, but still tight & crunchy.
Completely different sounding pickups, but both killer & worth a look if the JB doesn't do it for ya.
