I think he should get the best he can afford for what he wants so first if he can get it I'd say take the 75w version too. It has more features than the 15 or the 30. Don't let the "15" fool you. This amp gets pretty loud. Way louder than you'd expect by just looking at it. So yes like 6strngs said the 75w would get up there. I reccomend buying headphones and playing with them if you have neighbors that will complain during the day. However a ten ft cable is handy. Sometimes you need to move around.
