wrt the variable resistors (potentiometers), I think A and B initial letters
more likely represent two different sections of the circuit. The only forms of
pots that I'm familiar are the logarithmic (audio) and linear. Can't see how a
B implies linear.
whether or not you can see how it implies it, I can verify that that
is in fact the case
A = audio
B = linear
I've got a couple of each sitting right here, and i've seen plenty of
them in guitar effects circuits.
