I am not much for modding basses, but I really like my Affinity J-bass V, and I honestly have much more important things to spend money on this year than bass gear. I love the way my Affinity plays, and I think its B string is quite solid. My main issues are the lack of shielding and a somewhat thin tone compared to more expensive basses. This means my priorities are a great shielding job and either new pickups (Barts or DiMarzio Ultra Jazzes,) or new pickups and a two band preamp. I'll list my options in a poll. I picked Barts and DiMarzio pickups for a more modern and quiet sound plus they are fairly cheap. I also picked Bartolini and Aguilar pickups because they are fairly inexpensive and are consistently good.
