Well I'm 16 and gigging. At home I set it at about 1 1/2 depending on which axe I'm using(the LP is louder). Dirt channel(master) at about .5. My amp is very loud.

Gigs: Outside and without a mic- 4-8
Inside without mic- 3-6

I have no complaints about my setup either, I love it, sweet sounding, more power than I need, its perfect.
