So I see all of this talk about the svt 3 pro being under powered. Is this coming from people running it at 8 ohms? I run mine through an American made ampeg 610hlf (4ohm) and it slays. I don't have the factory tubes in it anymore, I've upgraded to jj's but still with the factory tubes this thing was LOUD. I've been told to turn down even with the master set low in bands with guitarists running full Marshall, Mesa, and orange stacks. I just don't get it. I like the tone of the 3pro more than the 4pro and I've never needed 1 more watt than the 3 pro gives me. Am I a lucky duck or is everyone else doing something wrong?
