So I'm thinking of adding some fiberglass insulation to my Sunn 412L. What will adding insulation to this over-sized cab do? I'm trying to reduce [perceived] bass response from the cab and accordingly I recently installed casters to the cab (which helped). The cab is just incredibly bassy due to it's size, so will adding fiberglass (or anything better) insulation to the interior walls of the cab add or reduce bass response? And yes I am a newb to this sort of thing.
