It is a vibro king. I've had a vibroverb too but gave it to my best friend years back. I've known him since high school and we've played together for well over twenty years now. I wish I had it back but I know he loves it dearly. I guess the amp is probably over ten years old by now and he has used the crap out of it. Still works and sounds great too. On a side note my wife absolutely hates my makesift bookshelf. I've always told her no one will ever see it....at least that was my argument before she read your post TV... Now she is TELLING me to get rid of it. Man oh man why did I have to post that pic...
