Shure Model 300 by John Eppstein
This vintage ribbon microphone is often overlooked when classic ribbons are discussed. It has a typical figure 8 pattern, bass rolloff switch, and 3 way impedance selector.
The smooth, detailed, yet not overly bright response is what one looks for in a good ribbon. It imparts a musical "roundness" to the sound without exaggerating the low end or sounding excessively dark - it is my favorite microphone for taming the harshness and sibilance in my vocals while still retaining a clear, detailed sound. It is also excellent on acoustic guitar, other stringed instruments, and room mic applications. Like all ribbons you need to take care with the element and don't apply phantom power. Since the output is low (typical of most ribbons) it requires a quiet preamp with good gain. It works fine into the preamps in my Soundcraft DC2020 console, but requires the gain to be maxed.
Since it isn't one of the popular, excessively publicized mics like the classic RCA and Coles mics you can sometimes still pick one up at a reasonable price.
Impedance selections: 38 and 150 ohms and "High Impedanmce" for use with all amplifiers
Bass rolloff switch
