The clarity of the sound is obviously better than the recommended LM386 IC that people use for a small guitar amp DIY that i've found in Google. Dual speaker in the video is just a demonstration and it is possible to make a mono output using a different setup of the circuit schematic. For the time being i will stick to this until further improvement in the future. I would like to make this for real for myself so that i can fine tune the distortion and tone control.
There will be improvement in the future for this circuit possibly with the addition of pre-amp circuit to allow controlling the tone and also alter the sound clarity.
