   **  It's not actually.   
      
    Seems like a ballsed up version with missing resistors that will be become

   The "Baxandall" tone control design was published in Wireless World in   
   952  - it used valves. The network is different to the one in the link above   
   and produces variable turnover at both the high and low ends of the range.
