The RC type tone control circuit is as shown in the figure. The tone control circuits are divided into the RC type, the input series voltage feedback NFB type, the input parallel voltage feedback BAX type. The RC type tone control circuit which is as shown in figure 2-42 is composed of the low-pass filter and high-pass filter (composed of the capacitor and resistor), the filter characteristics is controlled by the potentiometer. This kind of circuit has the low input impedance and higher output consumption, so you need to connected the buffer amplifier with it. The rated consumption of the filter is about 15-20dB, so the input buffer need to have the wide dynamic range.
