I've been playing bass for about 15 years. Even with that experience, I find myself with questions that I should have had answered years ago. So, without further adieu, here are some off the top of my head. 1. On a preamp, what is the effects loop and how is it utilized? 2. Active vs Passive. I realize Active pickups use batteries and Passive do not. But other than that, what is the difference? I'm sure there are other "beginner" questions out there. Let's hear some of them!
