This is the most common of all modern tone control circuits, and was named after PJ Baxandall who came up with the idea many years ago. The original design article was entitled Negative Feedback Tone Control - Independent Variation of Bass and Treble Without Switches , and was published in Wireless World (now Electronics World) in 1952. This type of control is fully symmetrical, and there is no interaction between the controls, unlike the older passive controls. When centred, there is neither loss nor gain, and the opamp acts as a buffer. Frequency response is absolutely flat, provided the pots centre precisely.
