From any number of places one can buy high quality 'electret condenser microphone' elements. These are the basic building blocks of recording mics.

You will need:

• An electret microphone element;
• 8' lighweight shielded cable;
• plugs to match the jacks on your amp, recorder or mixer;
• 9 volt battery and battery hook-up clip;
• an amplifier or mixer;
• assorted resistors and capacitors;
• packaging supplies;
• hand tools, soldering iron and electrical tape.

If you have a choice of models when you go to buy an element, look for the highest signal-to-noise ratio and a flat, extended frequency response. If you have a choice between 'cordioid' (directional) and 'omnidirectional' pick-up pattern bear in mind tht the omni models usually have a flatter response curve - the quality of the sound tends to make up for its lack of directionality.
