Has anyone tried these? I went to GC today and was hoping they'd have them to try, but they didn't. I'm debating between getting the Classic Rock one or the AC30. I tend to play a lot of classic rock, neoclassical, rock and metal, but I don't really want to buy two. I was listening to some youtube clips and the Classic Rock one sounds pretty solid for a good practicing tone I guess... but I couldn't find any AC30 clips that sounded that great. If anyone has any tips or warnings against these, it would be greatly appreciated. I was hoping to snag one this weekend. Thanks!
