Can anyone post some pics of the ACM-3 opened up? I haven't had time to do this. The folks at Edcor (transformers) want some input as to the size etc. Being so busy shipping, the only mic I have actually used so far, is the "510" I was only one of two people that ordered this mic. It's the USB mic, and I use it via "Gizmo project" for almost free phone calls anywhere in the world. Just yesterday I was talking to one of the engineers in China about our mics.
