Introduction: Active Tone Control Circuit

Picture of 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.

Step 1: Making Print Board

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.

Step 2: Drilling Holes

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

Step 3: Putting Circuit Into Box

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 :)

This is only for school use... all you need is +9V and -9V(from generator)..

Nice build. Very useful for guitar effects etc. Would have been nicer if there was a demo video though.
