Brighter and louder, for sure, but this comes at the risk of a poor taper, if the pot value is too high for the signal impedance.
If you're not sure, just use 50k. That value works for most active things.
There is no risk of damage with any pot value, however. The pickups handle zero and infinite impedances without issue, so they don't care about any finite value in-between.
