I'll chime in. I also have a stock 55-14 and a 55-02 with Nordstrand pickups and a Bartolini NTMB preamp. I find the 55-14 to be more 'polite' and neutral and the 55-02 is more 'aggressive' and grindy. I use the 55-02 when I want to use distortion or cut through the mix. I'm not sure if it's more the pickups or the pre and I've never played a Stingray so I can't compare the two. When I sweep the blend knob on the 55-02 I can definitely hear a change in tone whereas on the 55-14 it is very subtle.
Thank you. This is good info. Sounds like those Nordstrands may be helping to add more of that high mid grind and aggressive character that I am looking for. I do find that my 55-14 sounds similar with the pre amp set flat and engaged or turned off in passive mode. I am thinking the neutral character comes from the pickups. Sounds like swapping them may be worth the try. Although you have the Bart pre in that bass, I would definitely not consider the Bart electronics to be aggressive in my fretless. I have no intention of modding that particular bass though, being that it is a vintage Lakland.
