My second bass (my first one lasted me about half a year, it was a 5 string and I wanted to move down to 4) was some sort of Schecter. It had EMG-HZ pickups. For the longest time, I was mislead into thinking that these were active pickups, as it was advertised that this bass had an "active preamp." My third bass, which I have had since '03, is a Lakland 44-02. It has a Bartolini MM and J. Lately, I logged on to the forum to ask a question about potentially swapping out the Barts for a pair of more aggressive Basslines, when someone asserted that my pickups were probably not active. At first I wanted to interject and insist on the contrary, but then my certainty on whether or not my last bass was active stopped me from doing so. Does my bass have active pickups? How would I find out? Thank you.
