This question for what I can find hasn't come up since 2002 and things have changed since then. I like sound of the bass' bart mk1s to an extent but sometimes the low end seems to woof rather than have a smooth low end. Does anyone know if nordstrand has pickups that has smoother low end and great miss that fit without re routing. And if not are there any other suggestions you folks have for some better pups. I like the passive with an active preamp if that helps and I'm not against changing the pre amp too if needed.
