Ill have a review up soon but wizard have just started making the rather amazing 'gaffer'. Which is a split coil p bass style humbucker in a jazz casing, I have two, one in each jazz neck location, and they sound huge!! Solo'd they turn my jazz into a big, fat snarly p bass (think jj burnel, green day) roll back the tone and it nails that vintage tone beautifully. I've also found that if you get the balance with the bridge just right it really adds depth and bite to the both pickups on full core tone. Can't recommend it enough for any jazz. Don't think they are on the website yet, although will be soon, but if you call or email wizard and ask for a gaffer Andy will sling you one. They are silent and look nice too with raised poles and a nice rounded edged casing.
