Checking my ears

January 4, 2012

Bought this on a whim to double check my ears to see if they were as good as I think. Well, found out I'm still there. Did amps via VOM & checked my ears to see if I had speakers & sub in the ball park. This is good for a novice and will help teach them what stuff should sound like.
