Title says it all really, just wondering if anyone knows of any mics with a frequency response curve that has a bit of a boost around 500hz (400-600) most condensers have boost at high end and seen bass mics with boost at low end (150hz and lower) is there any with 500hz boost? doesn't matter about type (cardioid,ribbon,dynamic etc) and preferably the rest of the curve to be flat or slope off at ends, just no other boosts other than 500
