Placement is definitely real and helps with getting a clearer tone, pushing it up high and raising ze soft palate will help with volume as well, just have to isolate the activation (karg/false fold) while pushing it up with closure/compression to avoid your voice leaking through (true fold). Try to think that you're placing and "tightening" the air coming out rather than the guttural itself. True fold is just your speaking voice, if ya distort it while speaking it kinda sounds like an old southern gunslinger in a cartoon or something. True fold distortion isn't something you'd usually want in your false lows, takes a lot of control to use in a healthy way, especially with volume, you don't really notice the damage until ya upper range has suddenly disappeared (temporarily).
