Your hearing's sensitivity to loudness is logarithmic so you can hear a pin drop but also hear something that is extremely loud.

The linear potentiometer is not a logarithmic volume control. If you turn it down from max to half then the audio level will be reduced only a little, but a log volume control will turn down the audio level quite a lot. If you turn up the linear pot from minimum to just a little higher then the audio level will suddenly turn on fairly high, but a log volume control will turn on the sound level only a little.

Why don't they install log pots on guitars? I've always wondered why that was the case with volume pots...

Aren't electric geetars played at full blast with tons of overdrive distortion? They never turn down the level (they like the awful fuzz sounds).

The input of the amplifier has a log volume control.
