The one thing most young bassists fail to understand- wattage is far less important than speakers, and more spkrs equals more volume. Comparing a 2x10 combo amp to a rig with twice the number of spkrs is apples to oranges. Of course the 410 will have alot more volume. But in the same vein, you don't want to use up your availoable power on ONE medium sized cab, such as a 4 ohm 410. An 8 ohm 410 will be almost as loud, but leave room to add a 2nd one, to really increase your output. So, big +1 to CLPeave's 300-500 watt head paired with an 8 ohm 4x10 advice.
