I recently played a few recording sessions using M221 and M300 Microtech Gefell mics.
They sound amazing and I was so impressed with the warm, rich tone they captured from my Martin OM Custom and Kenny Hill Stand-Up Signature.
When using these mics in pairs they have an exceptional depth and transparency. I have been looking for this particular sound and am thrilled to have finally found it! Since I'm playing all different styles and guitars, I need something that is able to capture my varying attacks on strings, different tone colors and strumming styles.
I'm very happy to have the chance to use them and they will be my preferred mics from now on!
Here is a photo from the session with my Martin!
