I just graded all my FETs with that 9 volt battery method described here somewhere. The NOS Fairchilds had IDSS ranges from 2 to 6. The NTEs went from 5 to 8. So I bagged them all separately and labelled them.

I set up my two completed mics in M/S configuration with the top mic in cardioid and the bottom in figure 8. Here's a short snippet of recorded acoustic guitar with no EQ, compression, or reverb -- just levels adjusted between the mid and side signals:

Mics were stock BOM and styros with Maiku k87 capsules. Thanks for a great board and kit, Dan!

I've never found there to be a enough L/R information to record an acoustic with that technique.

Hi Ricardus. I'm sorry the technique never worked out for you. Here is the mid/cardioid only track. It's mono and it's wonderful. I chose the Blumlein/Lauridsen technique to get a stereo spread and I think it worked out beautifully with the guitar about two feet away from the two mics. (It's even better with reverb). To each his own, I suppose...

 What would be cool is if a mod would move these last 4 posts or so (from when you posted your initial msg about it) to a new thread in the forum area talking about production techniques. I have a lot to say about this and it would be more appropriate there.
