The Vactol pot will only work in real high impedance apps... you will not
get a good
'end resistance' with it. In tone control apps that would mean sacrificing
a tiny
bit of the possible cut and boost...

...and you are right about the setting... people will just crank the knob
until they
get a good sound (or a ~bad~ one :^)
