I am trying to teach myself electronics, namely audio filtering, and I came across this circuit. Now with my limited knowledge the 'volume potentiometer' (that's what it is explained as) seems to be in parallel with the resistor forming the high-pass RC filter so would this mean that this circuit is wrong. I think that the output of each filter needs to be buffered and that those outputs should have the poteniometers on them? All the pots in the circuit are 10K Log's
