/*I built two mics with the same body and grill and the same capsule a tim campbell ck12. One has the elam 25x circuit th other one has a bit of a mixture of a brauner vm1, Oliver archuts C12VR mod wih some ideas I got from seeing the mk7 schematics. I put a pikatron 9.5 : 1 tx inside, the bass is great, snr is great but the highs are far not as good as in the elam style mic. I put 1G's for the high value resistors. How do the high value resistors interact with the circtuit ? Do they also influence the hi freqs. I thought they just change bass response and snr ?

..so I didn't like the sound of that circuit. Here is something I came up with, can anybody tell me if this would work as an ELAM with variable pattern control ?
