Re: Test what you think you know: Part 2
Because the people doing it don't understand how they are changing the behavior of the mic. I have never heard anyone using the technique actually discuss the type of foam used. I have seen towels used, sweatshirts used, bubble wrap used, both open and closed cell camp pads, and any assortment of packing materials. I have even seen aurelux used, an expensive way to quickly suck.
My opinion, based on my experience, is the resulting sound sucks. If what you want for the bass is a muffled thud, with no definition, no attack, and no sustain, this might be the technique for you.
Some people will trust my experience, others will want some reason. I think I can now say, based on this, that blocking the ports changes the response of the microphone. We can quibble all day about how much different materials will block the ports, but while that is happening I am just going to walk over to my mic box and pull out a pro35 which is my quick solution for a bass with no pickups that the player doesn't have their own preferred method.
