One thing to note about EMG active pickups, the ones with the buffer in the pickup housing, is that the pickup itself can use lower strength rail magnets which means less “pull” on the strings and better sustain. The buffer preamp compensates for the lower signals from the coils. I don’t think they all do that, but I have an active P model in one bass and it’s really good. The system as a whole is not equivalent to the standard passive pickup(s) volume & balance followed by an active EQ - you don’t have the pots affecting the tone.
