I picked up this amp yesterday at GC and it sure has a lot going on. This is literally the first time I fired it up. I mostly go through the preamp switches between USA/Vox/Brit settings. The British setting is noticeably louder and beefier. The Vox is quite sparkly, especially on the clean channel. The USA is pretty Fendery - go figure. I'm playing through a 1x12 cab loaded with a Madison Opus speaker (think V30-ish).
