I know this has probably been discussed a million times, but..... I've never owned an active bass, but lately have been wanting more tone options. Has anyone out there got an opinion on the EMG P & J pick ups which include their own pre-amp, etc. My instrument is a Yamaha BB1000 1978 model with both P & J pickups which are passive. I don't want to have any new routing done to accommidate a larger pre-amp.
