In case anyone is looking to buy a lower price class d head. I purchased one of these 6 months ago and have used it for10-12 shows now with2x410cabinets and it's amazing. I started out replacing my svt4 many years ago due to getting older and the thing was a pig to load and unload. I love the mark bass heads I have also used for the last ten years. This head seems to be as good as the markiii I've used for quite a while. Thought I'd give this head a test since I swore off peavy many years ago. It has proven itself so far and I have purchased a second before the price goes up for certain when they catch on. Only been 6months so can't speak for longevity but I have a good feeling at this time.
