Fender American Standard Jazz bass pickup question.

[Blueser]

Which pickup wind would these stock pickups be closest to in their tone and power (50's, 60's, 70's, or none of the above)?

Just trying to get an idea as to where these pickups fall on the tone spectrum. I know they don't get a lot of respect around here, but I think they sound pretty damn good with my setup.

I thought of going the Nordstrand route with a set of NJ4 pickups, as all of the clips I have heard of them demostrate some amazing tone and clarity, but I want to make sure that I get the depth and warmth as well.

Thanks in advance for any light that can be shed on this.

Regards,
Dave
