I play through a Sunn head, don't recall exactly which model it is, but I think it's a lead. From the Sunns I've seen, they are very very loud and great for loud rock/punk/etc. or any other kind of music where you're concerned more with volume than with getting a specific sound. I'm not an expert on "tone" but I have a feeling that other people on this board would not recommend them for a superclean sound or anything. But if you're looking for cheap and loud, I would recommend the Sunn, I'm pretty happy with mine.
