I have dimarzio ultra jazz fives in my warmoth custom. The only way to avoid string pull and the consequential unwanted overtones on my E and B strings is to have the pickups decently far away from the strings ( about 1/2 " on the B side for the neck pickup and a little under that for the bridge pickup). The output on this bass, also equipped with an aguilar OBP-3 is very low, in fact my passive fender jazz four string blows it away output wise. The pickups on the jazz are way closer to the strings. Is this normal for ultra jazz pickups? (low output yet strong string pull on the B) If I raise my pickups the B string starts getting wierd overtones.
