Hey guys, I have a CIJ 62 RI fretless. It is a cool bass. I was gonna sell it a while back, and then let a friend borrow it. When i got it back I havent stopped playing it. Really getting into the fretless feel. My question is, if I wanted to change out the pickups for something sounding a bit better, What would be a good set? I am asking this to hear opinions from peeps who have had experience with this. Just wanting some recommendations and feeling on different sounds. Obviously because this is a 62 RI fretless I was inspired by Jaco when I bought the bass. My playing style is nothing like his but I just liked the whole dirty, gritty, vintage fender sound he was making. I want something that could be a bit more punchier and growlier than the stock pups. I have a set of american vintage pups lying around. Obviously they wont give me much more balls than the standard ones I got in, but is it worth a shot? Messing with the integrity of the bass? Maybe a pre-amp? I have a fretted jazz with dimarzio ultra jazz and an audere in and its very modern sounding... Anyway, what do you guys think of all this? Thanks A.
