Volume Potentiometer

Jumpers mean never having to say you're sorry.
The volume pot is (as most volume pots are) a logarithmic curve. I'm not entirely sure which direction I want that to go since the volume response curve on the LM4875 is partly exponential but is mostly linear at higher volumes. So I punted and made it something I can change later.
Each of these three-position jumpers connects the potentiometer to one end or the other. By bridging the center and either the top or the bottom, and the opposite for the other one, the volume pot can be wired in either direction and I don't need to figure this out now.
