I found that a capacitor in series with the neck pickup works, the smaller the cap the more bass gets cut, BUT because caps alter phase you might find that your middle position gets affected and not necessarily in a good way. A cap that's small enough to get a good tonal balance between the pickups might add a hint of that out-of-phase sound when both are on together, ruining the beauty of the middle position. It's a compromise.
I solved the problem by taking a fat old Dimarzio P90 that ohmed out to around 9k (pretty high for a P90) and unwinding it in steps down to about 7.2k. That cut the bass & muddy low mids and boosted the sparkle factor. That's what's in the avatar guitar now, along with a Parsons Street bridge p'up at 8.2k.
Lindy Fralin sells 15% underwound neck P90s, but the mini humbucker solution is what I found worked best in my LP Studio.
