I'm going to be putting together a bass and have most of the stuff all sorted out. It's going to be a rear routed j-bass style body with Nordstrand big singles. The only question I have left is what is the main benefit of the following pickup configuration ( outside of the active electronics ). I have a Lakland DJ4 that I use for all typical J sounds. The big singles give my other bass a much different vibe that I like. What is the biggest tonal change between having them in the standard spots vs. something like this sadowsky?
