You should always use audio pots for volume control, otherwise you will find that the volume does not change smoothly as you turn the pot up and down. With a linear taper pot, you will find that the volume increases slowly from 0 to about 60 or 70 percent, then increases rapidly from that point on. This is because there isn't a direct relationship between resistance and volume in a passive circuit (which is what a guitar with passive pickups is). Audio taper pots compensate for this, and give you a consistent volume change throughout the sweep.
