As DarthPhineas said, there are plenty of pickups designed with the JB as inspiration, but there is no other pickup exactly like the JB.
Ignore the "scatterwound" comment, it was out of place. NO "JB" models (outside of Custom Shop special orders) are scatterwound and NO pickup that IS scatterwound will ever sound exactly like the real "JB".
Luke Duke is hitting on the same thing I mentioned earlier in this thread... If you want to recreate the sound of a JB that's been used and abused for 30+ years, get the Antiquity. If you want to experience what a brand new JB sounded like 30+ years ago, get the 35th. If you want to capture the sound of every JB made in the past 20 years, get the regular production model. If you are inclined to whine about the minute differences between these off-the-shelf models and a true "vintage" model from the late-'70s/early-'80s, buy used and quit complaining that the "new" stuff doesn't sound the same.
