I have a P bass with EMG P/J pickups and a BTC preamp. I keep them at the lowest "response curve" setting, and played through my rig this is still really bright to me. I find myself still toning it down a touch. I prefer a rich, defined, slightly muscular tone so zingy doesn't work for me.
I tried each setting while listening to the bass through headphones for a more even representation. I just found that each subsequent setting got brighter (until it skirted dog whistle land) and I didn't care for them. I don't slap or tap - maybe these settings help define those styles of play. I found no realized benefit hitting 10K Hz.
Of course, your mileage may vary. The only thing to do is hook the bass up to your amp (leave everything flat), flip them one at a time and adjust your treble control to see how it impacts your sound.
I wish they could just say - "boosts 3K Hz", "boosts 8k Hz).....
Honestly, I find trying to figure out the tone mural they show for each setting is confusing.
