The Advanced Audio CM48 fet is a large diaphragm, 3-pattern fet condenser microphone featuring our AK47 capsule, which is based on the venerable Neumann U-47fet. The CM48 has the same response as the U-47fet but with the added advantage of three pickup patterns. We have also improved the stand attachment by fitting the threaded isolation mount that we use on our CM87 and CM47 microphones. The CM48fet can be successfully used to record vocals and bass and guitar amps, and is also an excellent room microphone. Capsule The CM48 features a double-sided, single back-plate 32mm K47 type capsule with a response identical to the original K47 capsule used in the U-47fet. Circuit The CM48 uses the same discrete, two-stage Class A transformer amplifier design found in our CM87 microphone. The AK47 capsule is 3-4dB less efficient than the AK67 capsule and features the cylindrical U-47 type head grill. This combination allows the microphone to handle higher sound pressure levels than the CM87. The CM48 also has a -10db pad as well as a 100Hz rumble filter. It comes in a rugged aluminum flight case with a very robust shock-mount.

CM48 or CM87 - user/owner opinions please!

...much anyone, it's not usually the most exciting of choices, so I guess what I'm really wondering is if the CM48 would be a bit more interesting/exciting, while still working on as wide a variety of voices as the CM87 would? My main concern is that the CM48 may have a bit too much vintage...
