/* Linear and Audio Taper */
The following lines were added (+) and removed (-):
Be sure to use an "'''audio taper pot'''" for volume control.The way to identify an audio taper pot is to set it to half rotation and measure from center to each end with an ohmmeter. If the resistances are approximately equal you have a linear pot. If the resistance from the counter clockwise end to center is about 10% of the total and the resistance from the clockwise end to the center is about 90% then you are holding an audio taper pot.  The way to identify an audio taper pot is to set it to half rotation and measure from center to each end with an ohmmeter.
