The tap on the vol pot is for slight equalization of the audio at low volume. It rolls off the high frequencies a little at low volume.
On the old stereo receivers it could be switch in or out. It was called "loudness contour".
Using a volume pot without it if you don't like the sound you could add a cap of similar value at the high side and change it's value to suit your tastes. You may not even notice any difference unless you are listening for it.
