It still kinda holds up well for what it is, and what it was at the time. No, it's not a Neumann sound by any stretch of the imagination, but, if CAD had used the original capsules I speced for the mic (actually, I did originally call it "The Mic") instead of the Primo capsules they used, it would have been a lot closer sounding to a Neumann than it is.
The new Studio Project multi-pattern mics are a lot better value for the money, but at the time, I was pretty proud of coming up with a multi-pattern mic for the home market for under $350 with 4 patterns, bass rolloff, and level pads. And that was in 1987.
I dragged it out to compare it to the SP stuff, and while every one of the SPs beat it (I felt), it wasn't THAT bad as a utility mic perhaps.
If you can find one used for cheap, it's not a bad mic.
And timc, of course it sounds like an electret; it IS an electret. Actually, just a pair of back to back, small electret cardioid capsules made by Primo.
