I got a Peluso P12 about a year ago--a friend of mine just bought a telefunken AK-47, and was kind enough to let me borrow it for a little side by side comparison.
The signal chain was as follows:
Female vocals -->mic-->ISA 428 --> ISA convertors --> PT LE at 24/44.1
No compression; impedance was set to "low", the vocalist stood about 10 inches from both mics. Each had 1 hour to warm up (the mics, not the vocalist

). The only processing was a slight gain boost on the peluso (about 2.5 dBs) to match the Tele. Then both files were normalized.
Not real high end pres and covertors I know, but it's the best I have!
I was really surprised how similar the two mics sounded-I was expecting a bigger difference--or maybe my ears are that bad! The P12 sounds a little brighter on top, and the Tele is a little thicker in the lower mids. I'm curious to see what others think.
