Cascade MX-22 and MX-33 LDC condenser microphones.
Here are the photos of two older Cascade LDC microphones. The MX-22 is a cardioid only microphone while the MS-33 is a multipattern mic. I acquired the MX-22 from eBay and shortly thereafter acquired a pair of MX-33s on eBay. The MX-33s were from the estate of the late Gary Loizzo who was the lead singer of The American Breed, formed in the mid-1960s. Loizzo then went on to start his own recording studio called ‘Pumpkin Studios’ in the early 70’s and become a two-time Grammy-nominated recording engineer.
There is absolutely no information on them from Cascade. I assume that they were imported from China and were a generic microphone that was customized. I tried a little more research and discovered that they were built by Feilo in China. Feilo describes their services as follows: We specialize in contract manufacturing of microphones for distributors, retailers and manufacturers seeking to private label our products or outsource their manufacturing.
The MX-22 appears to be a Feilo Z-2200 and the MX-33 appears to be a Feilo Z-3300. The microphones appear to be identical, but I don’t know if any of the components had different specs. According to Matt McGlynn at Recording Hacks, the MX-33 and Feilo Z-3300 are identical to the Advanced Audio CM-87, at least from looking at the pictures. Both of the microphones feature discrete class-A circuitry and a transformer-coupled output. They have a 1.07″ diameter K67 center-terminated type capsule.
