This is saying a 220k log b potentiometer for the tone pot VR8, correct? That is such an extremely odd value, but I don't see that sort of notation very often either and I wanted to make sure I'm not misinterpreting. Thanks!

According to the table given on this page, "A" stands for logarithmic potentiometer (Audio), and B is standing for linear one (In Asia and America at least):
