Too much education calls for theory when one is not needed.
No, no theory, just plain common sense.
Lets go to the facts. Here
The Secret Life of Pots you can find this

500 k linear taper pot and 500k audio taper pot have the same effect only when both are either on 10 or on 0. Any other setting between 0 and 10 is different for these 2 pots.
Further, tone pot is just a simple variable resistor.That is why this graph explains its effect properly.
Now, MY theory/thesis : Most people (~90% of overall population with regular hearing ability) start to notice difference in highs when you turn AUDIO taper (LOGarithmic taper) used as a TONE pot in a guitar from 10 to 8 or even from 10 to 7. [end of theory/thesis]
On this graph one can see (y axis) that this equals ~ 32% for 8 or ~23% for 7 and this translates as 3 or 2 on LINEAR taper pot, cause it is - linear.
So if anyone would like to have usable range from 0 to 3 or from 0 to 2 using LINEAR taper pot instead of having usable range from 0 to 8 or 0 to 7 using AUDIO taper pot he/she is strongly advised to do so - use LINEAR pot as TONE pot in his/her guitar. To me, that is
nonsense. And the fact that this is rather stupid should not stop anyone for doing it that way.
Now some notes.
1st note: all this is valid only for those who actually use their tone pots/who DO NOT keep their tone pots always on 10. If you keep your tone pot(s) always on 10 use no load pot :
Project Guitar :: Checking DC resistance on your potentiometers
2nd note : estimation that effect of audio taper pot used tone pot starts at 8 or 7 is based on bedroom guitar situation. any real playing situation live with at least bass and drums bring these values even lower - to 5 or 6. go figure.
3rd note : TONE pot in a guitar is practically VOLUME pot for particular freq range. hence audio taper should be used just as it is used for volume pot
I really do hope
"Linear pots for tone are pure nonsense. You do not want any other than audio taper there." is much clearer now.
