I was a bit sceptic when I brought these pickups. I have now owned them for several years, and had them installed in different basses. And finally ended up having them installed in my old American Vintage P-bass.
The installation is the best ever seen. It takes me 10 min to install them to my bas, as the wiring is based on an "plug and play" system.
If you are on a low budget, and need a pickup with lots of sound oppertunities, and are not that skilled with your soldering iron, then these EMG P are the go to.
