Anyone know if one exists? Wanting one sounding similar to a Seymour Duncan SPB2 but need it in a Jazz Bass housing. What's closest to give me that P-bass thump please? I don't want a standard Jazz Bass pickup 'cos it can get quite close' nor am I able to fit (in this situation) a P-bass pickup 'cos if you want P-bass thump, you need to get yourself a P-bass pickup'. Thanks in advance!
