in passive guitars and basses the pots will be Linear for tone, and Logarithmic for volume - but they are interchangeable, it's all down to personal preference.
Tone pots are LIN because it's generally more useful to have a constant rate of change on your tone i.e. a 1/4 turn takes 25% of the top end off (there's more to it than that, but it's a whole other rabbit hole), whereas the ear perceives changes in volume differently, so using a LOG tapered pot is the norm.
Like I said, nothing will explode if you use a different tapered pot, but it's considered more useful to use LIN for tone and LOG for volume.
