Schoeps CMTS 301 U Stereo microphone 1969-1972 (around that time)

I am selling this lovely multi pattern vintage mic as I don't record enough with it. It sounds amazing and gives you a lot of possibilities. I used it a lot on acoustic instruments such as piano and guitar and it really just sounds amazing. And this mic is very easy to work with. Comes with PSU and shock mount

Info from an old add:

The SCHOEPS CMTS 301 stereo microphones were optimized for coincident stereo recording. Using a matched pair of specially-adapted three-pattern capsules (Cardioid, Omni, Figure of Eight), they excelled at X/Y, "Blumlein" and M/S stereo techniques.

Much of the direct sound reaches the microphones from significantly off axis when these recording methods are used. Thus their success depends on smooth, uniform frequency response at all angles of sound incidence – a hallmark of SCHOEPS microphones. Large- and/or dual-diaphragm microphones cannot match these qualities.

A particular advantage of single-diaphragm cardioids is their ability to maintain full directivity at low frequencies. Thus they can pick up all the interchannel difference information that is critical for the sense of spaciousness. By contrast, stereo recordings made with coincident dual-diaphragm cardioids tend to collapse into mono at low frequencies.
