Default Simple tone control?


"Tauno Voipio"

This is the classic Baxandall tone control.



** It's not actually.

Seems like a ballsed up version with missing resistors that will be become
unstable at full treble.


There is plenty of material if Googling for
'baxandall'.



** And like most stuff on hobby web sites it is bunkum.

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.
