Anyone have any insight on the dip switches on the EMG pre amp? I've read it effects the bass, I've also read it effects the treble. I assume different combinations of on/off render different results. I could mess with it and listen, but figured I'd get an idea here first. The bass is a 95 Q5 SPI SS with EMG pickup and pre amp. I assume based on the wired connections this is the original pre amp. I'm assuming this is also the BQC pre amp from all my reading (this bass is set up 3 knows, stacked bass and treble, stacked mid and sweep, volume). The board says BQA but from what I read all the boards say that.
Anyway, any insight would be greatly helpful. I'm adding pics.
