Active Tone Control Circuit

I'll show you how to make this circuit step by step. You will need:
2x10K
2x3.3K
33K
2x100K potentiometer
2x47nF
560pF
LM741
I'll show you how to make the printed circuit board for this.

First we will draw connections on board.Use a felt pen with acetone or nail polish.And a mixture for removing is using 12% hydrogen and hydrochloric acid.Then remove the paint with alcohol or acetone.

When we remove  the excess copper off the tiles we should drill holes where we later will put the elements.

we put the elements on the board ,linking potentiometers, battery, input, output and the on off switch and then we put the board into a box.Fasten potenciomettre input and output switch on the box, connecting any battery, close the box and you are done making this circuit!good luck :)
