The Shure M67 is a vintage four channel microphone mixer commonly modified for use as a four channel preamp in recording studios. First manufactured in 1968, these became a standard in the broadcast industry. The M67 was used to record Woodstock and many a tv news program. Still readily available on the used market, they remain relatively affordable. With plenty of vintage iron to yield that classic 70s tone, these units really shine as preamps.
The versatility of the M67 can be improved through a number of basic mods. The circuit layout makes it relatively simple to adapt this mixer into a preamp with four separate channels. Additional modifications to the gain staging of each channel make it useful for either high or low volume sources.
These units are reputed to be a bit noisy but by replacing a few capacitors, tightly twisting all wire pairs, and adding ferrite chokes, they was able to reduce the noise dramatically.
