Ok I have a discontinued Ibanez sr496bm on the way. Im replacing the pre-amp with a aggie obp-1 as for the pups their the dx6n and dx6b. Are the pups worth keeping? I was thinking about going with basslines phase 1 or 2 pups? But really dont want to spend any more money on this bass if I dont have to, hell if the bass sounds good with the stock pre I might keep that as well, however a few Tb'ers think otherwise. Thanks guys.
