Ok, I'm planning on getting a MIA Passive Jazz Bass, and I want to put EMGs in it. I'm going to get the EMG J Set, and I want to know if it will work with a volume and a blend, or if vol/vol is the only way to go unless I get the BTC/BQC. I also don't want an onboard EQ, due to the fact that I hate knobs, and I usually play with the tone knob(s) set flat. Also will these EMGs help me in getting a good cutting, growly mids tone? I'm going to start a metal/punk/hard rock band with some friends and need to be able to cut through easily.
I haven't tried the EMG-J. I did, however have a bass with two EMG-HB's in it, and it had a vol./blend/tone setup rather than vol/vol/tone, so you could probably do it. If you e-mail EMG, they usually respond in a couple of days, so it's worth a try.
I run a emg p/j setup, mostly 9 on the p, 6 on the j with a slightly scooped mid set up on my swr. When I need to cut through I just roll the j up a bit. This jumps the mids enough to get on top of the mix. Dunno about growl, emg's main claim to fame seems to be their uncolored clarity.
For hard rock, I'd go with an "in your face'" sounding passive pickup like DiMarzios (what used to be Model J---now DP123?) or Duncan Quarter Pounders. EMGs are probably too clean to get the sound you're after. The EMG pickups are prewired as v/v/t so you'd have to get a blend pot and rewire. Contact EMG if you want to do this, as they use lower vlaue pots (like 25K ) than what you would use for passive pickups.
