Let's say I want to upgrade one or both of the pickups on my bass. I'm not sure why yet, but that's part of the question. For me to know how the pickup works/sounds with MY bass, it MUST be in my bass, right? I mean, the wood, the strings, my amp, I'm sure other things that I am missing, are all going contribute to the sound I get, right? So, how does one "experiment", if you will with pickups, or, let's say I played another bass and I loved the sound that a particular pickup gave and I think I want to replace my pickup with that. There's no real way to try it out other than to buy it, put it in, and hope, right?
