Well it looks like a ok mic from the spec sheet. Never tried it myself, but I'd give it a shot if I ever come across one when I'm running sound.
One thing to keep in mind: The specs says it's frequency range is 20Hz-16KHz, but the frequency chart starts at 50Hz, so it's hard to say what the response is in the 20Hz-50Hz range if that matters to you.
I found one thread here where one mention the P2: Bass recording - what's your chain??
Here's the quote from the thread:
