DIY Electronic dot com today, We’ll like to present simple tone contron schematic and circuit diagram.
This circuit can apply to your sound application or guitar tone control.
The function of the circuit is 10M ohms pot P1 for volume and P2 for tone.
C1-4 Capacitor are control all rank frequency.
You don’t use PCB for this circuit then you can connect capacitor with solder at pin of each Pot .

Active Baxandall Circuit

baxandale+amp.gif

To overcome the substantial losses in the passive version of this circuit, which give a level response (with both controls at mid way setting) but at -20dB below the input voltage, it is common to incorporate an amplifier in the designs. Nowadays an op-amp would be a reasonable choice, with the Baxandall network forming a negative feedback loop to give the required gain figures over the necessary bandwidth. Various designs are possible with different values for resistors R1 to R4 and C1 to C4 in the network, depending to some extent on the output impedance of the previous, and input impedance of the following circuits.

With active circuits such as that shown in Fig. 4.2.6 the aim is to have the level response at 0dB so there is no gain and no loss due to the tone control circuit. The maximum amount of boost possible should not be sufficient to overload any stage following the tone control if distortion is to be avoided. The design of such control circuits is usually therefore, an integral part of the overall design of an amplifier system.
