Hello there. So, here i go... Ive been looking at getting into five string basses. Mostly because they handle drop tunings so much better than a 4 string. I need a little advice before i take the plunge into this new world of extra strings. 1) Why is it that most all of the ones ive found are active EQ basses? What does this mean? I understand active pickups, but what is an active EQ? 2) Are there basses where i do not need a screw driver to open the panel to get at the 9v battery? Im looking for something that is more of a pull on/ off or a clip of sorts, as if i go active, im pulling the battery out of the bass after im done playing it. 3)Can anyone show me some passive 5 strings, or is that out of the option? I really dont want to be buying 9v batteries all the time. Price range is probably going to be in the 2-4 hundred dollar range, and open to the used market. If i think of anything else, i will post it. Thanks in advance for any help in this situation.
