Function sequence (above, left to right) treble--bass--volume, turn clockwise to turn down, counterclockwise to turn up

The R1/R8 resistor is an input attenuation resistor. It is mainly used to control the maximum volume. It avoids overloading the output volume due to the volume potentiometer being too high. The size is not fixed, depending on individual needs. You can use a jumper instead.
