Is there any simple rules to follow (i.e. how there is when setting up a home theatre) when positioning an amp in your room to get good sound. Shoved in the corner of room vs on a wall; pointing towards you or away etc? I know a lot of people have theirs where it is convenient, but for the best acoustics.

Just wondering, google didn't produce anything.
Put it somewhere where its not cornered and away from phones and TV's. Or you could shove it in a corner and pull it into the center of the room when you play.
