Ok, thanks for clarifying. If you approach it that way, you lose any cut in volume you had active when you go from Volume Control mode to Tone Control mode, and inversely, you lose any cut in treble you had active when you switch over from Tone Control mode to Volume Control mode.
Have you considered using a dual concentric pot which allows you to have both a Tone Control and Volume Control in the same "single pot" footprint? See pic and link:
