I have a Marshall MG30FX and I was wondering what the maximum volume I could have it at would be without damaging the amp. The loudest I've had it so far is just under halfway round on the knob. I know it doesn't sound very far around but it's pretty loud and louder than I would expect from an amp this size.

If anyone could let me know that would be great.
It's actually a question of how loud until it sounds like crap. Keep it in your bedroon, for practicing scales.
