I just re-potted my strat 280N/280M/298B with 500K pots. It sounds MUCH better than with the 250K pots! The highs are much clearer and articulate and the bass is full. I did change the wiring configuration a little bit, but not that much. I especially love when each pickup is individually selected. So bright and clean. Sounds really good! If I put this pups in another strat, then I would definitely go with the 500Ks over the 250s.

BTW - this is an American Deluxe Strat. Alder body with a Maple Neck and Rosewood finger board.
