EMG HG35's?

These are the only EMG pickups in that shape that are passive, I think. I don't really like to keep a battery in a bass.

I have never tried the HG35's but I have a set of EMG Geezer Butler P+J pickups. Not similar in shape, but also passive. I think it's one of the best P+J combos I have heard.

That said, most people go to EMG for their active pickups...of which there are a lot to choose from. What sort of bass sound are you after?
