So this weekend I jammed with a new band and rather than haul my cabs one of the dudes said I could use his Emperor 4x12, which is rated 8ohm. I forgot to switch my VB-2 from 4 to 8 ohms. The cabinet didn't fart or blow or anything, which was a relief, but I did notice my head was pretty hot after about an hour of jamming. No harm no foul? Which piece of equipment would have got the short end of the stick if something went wrong? Did I shorten the life of my tubes?
