Presenting the "Shaunak standard micro preamplifier"!
This is a small signal amplifier. It was built with the intention of increasing the faint signals from my guitar and keyboard so that I could feed it into my computer sound card for recording. Just for the sake of it I added the speaker and I was pleasantly surprised to find out that such a small unit could sufficiently drive a 4" cone.
Its clear, neat, tiny and has amazing treble response! I coupled it with my portable CD player to make a gadget reminiscent of a gramophone! The base response is not the best though.
Here are twenty seconds of my very mediocore guitar strumming in MP3 format.

Ps: If anyone wants the specs/schematics leave a comment here. Ill draw and add it in...
