Yeah, the very first tone control simply would not work.....that is, as a control, as shorting out 0.15uF in series with 0.01uF will change the capacitance from 10nF to 9.4nF which would be barely noticeable and is less than the tolerance of the caps itself.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
