A500k audio taper potentiometers can be used for both volume and tone controls with humbucker and single coil pickups.
The A500K audio taper pots will decrease the resistance in the last 50% of the rotation. Many say the A500K pot is better to use than the B500k pot because it increases and decreases in a way that better complements human hearing. To understand this better, picture the A500k audio taper as a curved graph that increases and decreases gradually, then picture B500k linear taper as a straight line graph that increases evenly.
