SM57 mic position test

In the table the dust cap is on the right and element cone on the left. Moving down on the table marks the distance from the grill.
In the buttons the first number presents the distance from the grill and the second one how much to the left is the mic moved.
For example 1cm off 6cm mean that the mic is 1cm away from the grill and 6 cm to the left away from the dust cap (center point of the element).

Mic used: SM57. The cab is Carvin Legacy 412 loaded with Celestion V30. The amp is JCM800 2204 clone head.
Recorder Zoom H4, looper TC Electronics Flashback.
