So I found an Edge Q6 at what I thought was a good price and grabbed it. The good news is that you can get some good sounds out of it, but I have some questions for those who may have more experience with this bass. First, I notice that the bass and treble boost/cut knobs also cut and boost the volume when you use them. Is this normal for this bass? The neck seems to have a non-glossy finish, and I wonder what you use to maintain it. Mine has a little grunge rubbed into it, and I thought I might steel-wool it a little and oil it, but I don't know what oil to use. Also, if any of you have done mods, particularly a preamp change, I'd be interested to hear how it worked out.
