[QUOTE="SlugButter, post: 8792358, member: 678073"] It is basically the same for volume control. Your stereo has one for volume control, the amp gain, your bass knob is a pot. They all would be log/taper pots, but may have some different voltage ratings and resistance. Large container ships even use a pot on the control panel to steer the ship, which would be a linear pot. The reason to use a log pot for all types of audio volume control is because of the way our ears interpret sound pressure levels. If it’s a linear pot our ears will perceive huge jumps in spl as you click the volume up. The resistance has to taper off as you move up with the volume to compensate for the way we hear sound.
