Not strictly pickups, but pre-amps seem to get discussed in this forum a fair bit. I have a J-Retro in my latest J bass (Nordie NJ4SE pups) and the sound is terrific, I'm really pleased with it. The only query I have is when I switch the active pre in (with all EQ flat), there is a slight hiss noticeable, only quiet, but "there". Obviously EQ settings can increase or decrease this as you'd expect. It's definitely a hiss rather than hum and unaffected by touching the strings/bridge etc. The bass is shielded with StewMac paint and I don't think improving the shielding would make much difference as "it's not that sort of noise". Am I correct here? I know that any pre will always add some noise, but it just seems to be slightly more than I get with, for example, my SR4 3 band. It's not really a problem in a playing situation but I just wondered if anybody had tips for cutting it down. The pickup height and gain adjustments are pretty much set already, BTW.
