The Wunder Audio CM67 S is an exceptional microphone for vocals when a smoother sound is desired. The original U67 is prized for its warmth, this is also true for the Wunder Audio CM67 S. It is also excellent for drums (toms, snare, overheads), acoustic guitar and electric guitar. The CM67 S is a serious pro-studio workhorse because it has a very nice top and bottom end, and brings out a natural sound from any source. This mic is true to a vintage U67 with a modern upgrade, Wunder Audio engineered a switchable cardioid mode relay on the inside of the mic instead of on the outside of the grille. This mode produces a smoother more full-bodied sound. The pattern switch is still on the PSU, but the actual switch point in the circuit is directly below the capsule compartment. At the same time, it retains the eight different polar patterns found in a vintage M49, so it is like having two mics in one!
