First, I am a novice and I'm coming back to this project after several months. I'm attaching a pic of the schematic. The immediate question I have is what does the term Vb mean? It appears to have to do with attachments to the two pots but there are three others off of R2 and R3 and most confusingly off of the voltage divider at R12 and R13. I'm also confised by the voltage divider since it doesn't really divide except atVb.
If someone could explain Vb and the how the voltage divider works in this case I would be extremely grateful.
