The CM7 G (Glass Tube Switchable) Suprema is the latest evolution of the CM7-GTS. This mic is true to a vintage U47 with a modern upgrade, Wunder Audio has 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!
