I have the CA-Ugly preamp and CAFS and I have not been able to get the preamp to work properly. On my Sony PCM-M10 recorder it only shows the left mic picking up sound. I have plugged the mics directly into the recorder and it picks up the left and right. I have tried adjusting the nodes on the back (clockwise, counter clockwise and in the middle) and only the levels go up and down on the left mic. I have also tried three different 9V batteries (Sunbeam, Duracell, Energizer) and out of ideas on what to try.... anyone else have any ideas?
