Nordstrand Big Splits!
I love my Kingfisher. The stock pickups sound great when practicing at home (although not a lot of sonic variation from neck to bridge) and they look fantastic. However, when playing on stage they are a problem. They are very low output which is an issue if you are plugging directly into a PA system. Worse, they are extremely noisy around electronically-controlled lights.
I went for the Nordstrand Big Splits. They fit perfectly and it only took about 15 minutes to do the swap. I also added some extra foam under each pickup to firm them up a bit.
Wow - this is now the perfect bass. Since they are split coil, using just the next results in a true vintage P-Bass sound. Using both results in a modern J-bass sound. I couldn't believe the difference. When playing at home through a Fender Rumble on clean (not load), my wall pictures started shaking. It was tough forking out the $$$ for these, but I guess sometimes you get what you pay for. They also look great with their offset pole pieces. I couldn't be happier. This is now the perfect passive bass.
