hey, im a noob, but i can do a decent scream ranging from death grunt to like a dr roxxo sorta 3 inches of blood thing. i cant do a midrange well, cause it ends up sounding like a super intense high midrange scream. also when i scream i run out of breath real fast. about 5 or 10 seconds. any tips? btw, how do you exhale a pig squeal?
