What is the difference between a condenser microphone and a dynamic microphone when recording classical guitar?
Condenser microphones generally produce a higher-quality audio signal and are now the popular choice in laboratory and studio recording applications. A single dynamic microphone will not respond linearly to all audio frequencies. Some microphones for this reason utilize multiple membranes for the different parts of the audio spectrum and then combine the resulting signals. Combining the multiple signals correctly is difficult and designs that do this are rare and tend to be expensive.
