Amp settings

[daulton]

I have an orange terror stamp. I won it through wishgranted on the orange amp website. I've heard of orange amps and familiar with them, but never owned one till now. I'm in a sludge metal band and I need help with some amp settings. So for my terror stamp, at which o clock should I set the gain, shape and volume one to get that sludge metal sound? I really need help with this one.
