E string too loud

I've been wrestling with a problem - my E strong is too loud and bass-heavy. The G string has a similar problem, but to a lesser extent. - a bit too loud and present.

My pickups are Nordstrand NJ4Se's, my onboard pre is a Nordstrand, and I use DR Sunbeams for strings.

My action is fairly low, but my pickup height is fairly normal. The pickups have pole pieces that are slightly radiused.

The problem seems to be the radius of the fretboard, and therefore the strings. Since the E and G are closer to the pickups, they naturally get "picked up" more. I assume that the radius-ing of the pole pieces helps, but it doesn't seem to help much.

It seems logical, by why haven't my other basses had this same problem? Why is it this particular bass? It's a Warmoth build (done by me), but it's a pretty standard build.

I can always just raise the E and G strings, but since the fretboard is radiused, the action on those strings gets pretty high, and makes the bass touch to play (esp the g string).

I can of course tilt the pickups lower on the E, but that just exacerbates the problem with the G.

Could it be something else? like the preamp? Or the strings - Are Sunbeams like this for some reason? The pre seems unlikely, since it's just one string, but it could be a peaky frequency(ies) I guess, but it seems a stretch.

Are there any tricks to this that I'm missing for some reason? I've never really had this problem before, >20 basses.

 

The radius is 10".

Not boosting anything - all flat.

The distance of the strings to the PP is what I assume the problem is, but why have I not had this problem in such a major way before, even with smaller radius necks? And what can I do about it other than having high action on the 2 outside strings, which seems like a kludge.

Are these pickups known for this?

 

I did, yes. The preamp was purchased new as well.

 

Yep.

 

Around August of this year. (From Bestbassgear.)

 

Hmm, I didn't realize that there were different PP height options, very interesting. I will contact the shop, thank you!

By the way, I bought those pickups for the neck pickup tone, but it's the bridge pickup that really floored me.
