A Note About "Taper":
The A or B on the pot distinguishes if the pot is an Audio Taper (A), or Linear Taper (B).
Linear Taper means exactly that, when you rotate the volume/tone it will increase/decrease in a linear fashion.
Audio Taper will increase/decrease in a sloped curve fashion.
Either could be used for volume or tone, and comes down to a personal preference. Hope this helps!
