Baxandall’s Original Tone Control Article from Wireless World 1952

This article was published in October of 1952, when Baxandall was 31 years old, the design having already won him a prize 2 years earlier in a competition. His design basically relegated other tone control circuits to the scrap heap, although cheap passive, or non-inverting circuits still persisted well into the 1980’s, especially in low cost mass market products from Japan. Of course, now tone controls can be implemented digitally, but for the analog type, this remains the gold standard.
