Does the 50K pot limit the amount of bass and highs, does the 100K just give you more adjustment but in the long run do both give you the exact same tone?
Open, the two pots will do the same thing.
Turn them all the way down, and you're cutting twice as much with the 100k. Other than that they're just variable resistors and won't change your sound.
If you need that kind of adjustability, your pre won't suffer from it. It's not really necessary however.
