Ok I have a Squier 5 string P-bass (with 2 jazz pickups) that I've been customizing. Now I've wanted to put new pickups in it but unfortunately its not like any other 5 string jazz bass. Both pickups are the same size (3 5/8") which is the same size as a 4 string jazz bass neck pickup. I looked around and saw that EMG makes a pickup that is the exact size I need and they say it can be used in a 4 string bass neck position or a narrow 5 string. My question is can I use 2 of these pickups in my bass if theyre both meant to ben in the neck position? or will it not work? Heres a link to the pickup I'm considering Also they say its a "stacked pickup" what does Stacked pickup mean?
