I have a BN6 and I have struggled a little bit grasping the tone controls. Never had so many options on a bass. I feel like passive is too low of an output maybe so I use active but I seem to be missing my upper mods. My G and C string are not nearly as loud as my b and e string. I am continuously fiddling with the active eq to try to get an even response across strings but so far not much luck. If anybody has any insight/advice I would love to hear it! This is the best playing bass I have ever laid my hands on but I just need to master the controls.
