i cant think of a solution other than to roll with it. anyway when your music does numbers you can buy something better. after all good music is god music despite the mic. in fact, one can use terrible mics for effect, such as in stockholm syndrome. a verse features mark hoppus screaming at the top of his lungs through a shower at a low end 1950s mic. perhaps a sound like that will give a rough or melancholy or menacing feel.
