This video shows how to make, build and solder a super simple microphone preamplifier circuit. This preamp works well with standard electret microphones from a standard 9V Battery.
*UPDATE (April 2024):* As you can see, this is an old video. As this is still the most popular video on my channel, I am thinking about remaking it in better quality with more background information. Also, if you're interested, I'd make up a schematic and component list. Comment "2024 Remake" if you'd like to see a new version, comment "Schematic" if you want me to post a schematic.
