I decided that I can't afford to buy really kick-ass bass in the near future. so I'm going to upgrade my Ibanez sr900 bass little bit. My Ibanez is great bass to play, allthough the sound is bit crappy. I've been told that the preamp is the one to blame. So I'm going with the Aguilar obp-3. And that kinda preamp deserves new pickups. so EMG DCs. which brings me to my question. How does those work together? I know many Spector basses have obp-3 and EMG HZ pickups. But I like the DCs better. Does anyone have this compination, I mean DCs and obp-3. And also does the two batteries in obp-3 really affect anything else than the headroom? Sorry for my english. I'm not a native speaker.
