    Whats the defference between volume pots and tone pots. The guy at the local store said that they do the same thing, except one has a linear curve and one is progressive.

    Basically you could use a tone pot for a volume pot, you would just get your sound slower as you turned it up.

    is this true?

    A volume pot is audio taper.
    A tone pot should be linear taper, but can be audio taper.

    If you were to use a linear taper pot for a volume control, you'd find that the sound would get quieter faster as you turned down the control.
  3. And you would find if you used a linear taper (resistance change rate remains the same throughout turning of the shaft) pot on volume 3/4 of the control would be the first 1/3 of the pot. After that, not much change. This is due to the fact the ear is Logorythmic (rate of change is not the same amount at any given point) in nature and the audio taper is logorythmic in an opposite manner to counter this.
