Hello,
The mid signal is influenced by the mid pot (R42) in combination with C22, this forms a ballast for the mid range signals.
The Bass signal is influenced by the bass pot (R41) in combination with C21, this forms then the ballast for the bass signals.
The High signal goes though C20 to the treble pot (R40) this pot is acting as a kind of balance between the treble signal and the combined bass and mid signals.
I hope this clearifies the working of this type of tone control.
Greetings,
Bertus
