Complete DIY Microphone Kit Option
If you would rather purchase a kit that includes the mic body, capsule, capsule mount, and a fantastic circuit kit, see these two options:
S-25 - Transformerless microphone based on a Schoeps circuit
T-25 - Transformer-coupled microphone based on a Neumann circuit
Both of these kits are available in two colors, silver and black. Both have high output and low noise. The S-25 has clean and accurate transient response. The T-25 circuit adds second-harmonic saturation (which is a major component of "tube mic sound"), and does a bit of transient compression -- although neither of these effects are overwhelming, especially on a spoken voice track.
Both mics have an internal pad switch, enabling recording of louder sources without clipping.
