DIY Tone Control 6 Band Graphic Equalizer Circuit | Homemade Circuit Pro...

By making such a TC, this means that at least 5 Potents will be needed:

1. Potentio 1 to control Bass tone nada
2. Potentio 2 to control Middle-Low or Semi-Bass notes
3. Potentio 3 to control Middle pitch nada
4. Potentio 4 to control Middle-High or Semi Treble notes
5. Potentio 5 to control the Treble tone, or if you want to install ...
6. Potentio 6 to control Volume

A. Volume Potentiac Affairs Install Elko 1µF or 2.2µF or 3.3µF or 4.7µF on pin 3 (as input) and pin 2 (as output) Volume Potentiate.

Leg 1 Potentio Volume is connected directly to Ground (GND)

After the output is available from pin 2 Potentio Volume:

B. Continue by channeling to each leg 3 potentiometer tone control:

1. Attach the 152-size capacitor to the 3rd leg of the Treble Potential
2. Attach a size 332 capacitor to the 3 pin of the MiddleHigh Potentio
3. Attach the size 103 capacitor to the 3 leg of the Potentio Middle
4. Attach a 22K size resistor to the 3 pin of the MiddleLow Potentio, and 
5. Attach a 10K size resistor to the 3rd leg of the Bass Pot

You can try a size 103 capacitor that is attached to the 3 legs of the Middle Potentio with a 10K size resistor or a value that suits your middle taste.

The inputs to each leg of the 3 control potentiometers have all been installed, now proceed with:

C. Installing the Audio output from each leg of the 2 control potentiometers to the TC output:

1. Install the 100Ω resistor from the 2nd leg of the Treble Potenti
2. Install a 2K2 size resistor from pin 2 of the MiddleHigh Potentio
3. Install a 10K size resistor from the 2nd leg of the Middle Potentio
4. Install the 8K2 size resistor from pin 2 of the MiddleLow Potentio, and
5. Install the 1K size resistor from the 2nd leg of the Bass Potentiometer.

D. Installing Components from foot 1 of all Control Potentions to Ground (GND), this serves to ward off unwanted tones when the potentiometer is rotated to the minimum.

1. Install the size 103 capacitor from the 1st leg of the Treble Potential to GND
2. Install the size 223 capacitor from the 1st leg of the MiddleHigh Potential to GND
3. Attach a 1K size resistor from the 1st leg of the Potentio Middle to GND
4. Attach a 2K2 size resistor from pin 1 of the MiddleLow Potent to GND, and
5. Install the 3K3 size resistor from the 1st leg of the Bass Potent to GND.

In fact, this can already control the desired tone, but its function is still not perfect, especially for Middle, MiddleLow and Bass, because it is still necessary:

E. Installing the supporting components of the tone filter :

1. Install a size 224 capacitor from foot 2 to pin 1 of the Potentio Middle
2. Install the 154 capacitor from foot 2 to pin 1 of the MiddleLow Potentio
3. Attach a size 104 capacitor from foot 2 to foot 1 of Potentio Bass

As an improvement, it is also necessary:

F. Install Elko from the output coming from each potentio to the output that will be channeled to the Amplifier

G. When the Tone control has been installed, it turns out that the audio quality is small or weak, so it can be amplified again using a transistor amplifier.
