I have a Spector Legend5 with the EMG HZ jazz neck and soapbar bridge pickups. According to Spector, the preamp is a EMG B30. I love the play ability of this bass but not a fan of the tone. I think just replacing the HZ pickups with EMG actives would make a huge difference and sound closer to my Euro 5 strings. The current configuration is vol/vol/mid/stacked bass and treble Which model EMG active pickups would be a good replacement?
