I am flabbergasted that it literally took you guys years to figure out how to use this microphone...I mean really!?!? Don't you know what to cut or boost once you hear the sound? Okay, you can't identify frequencies but don't you guys experiment when you're not gigging...try different things just because?
You're not curious to know what will happen if you twist that knob with that mic connected and pointed at that instrument? You don't ask questions when you don't understand something?
