Build a 20W Guitar Amp (DIY)

The IC LA4440 was very useful and easy to use it as an amplifier DIY project. We build a guitar amplifier using this basic schematic from datasheet.
As you can see its a basic circuit. So we added a tone control at the audio input to control bass,treble and volume. Use our filter circuit we have given in the previous posts to join it with power supply to avoid the noisy sound. Use low noise guitar cable to prevent the loud hiss or distortion in the standby sound.
Parts we have used are available in the market in wide range.
Here are my pictures

Haven't drawn a schematic on computer for it. I'll post it soon as new project. So visit us again..!!
Next project is about "DIY Electric Guitar Interface"
