That man @JohnDaBass put it far more eloquently than I could ever do.
My 51 being the Seymour Duncan Custom shop hot stack has a 29.8k output which is ludicrously hot.
As a result I feel I can only play it with Flats and TI ones, and I normally play with a pick, but even with rounds the pick didn’t sound right. It a finger root note kind of bass, with great clarity, but I have a Tonestyler bass ten with it in position 4-6 back from open and I have to dial the bass back on my amp waaaaay more than others. I also cannot stack pre-amps like I normally do - this is a bass - compressor - amp pick up/bass.
Good luck!
