This is a YouTube video on prototype model on breadboard how to make basic guitar amp that runs on 5 / 9 / 12 volt batteries or 5 volt USB power source. The output is using dual speaker (stereo) powered by TEA2025B amplifier chip.

Output loudness is pretty decent as shown in the video despite using basic sub-speaker - and it can be improved using more advance circuit.
