I've had a few days, bought second hand by chance. I use the guitar with my old all-tube amp Faylon. It is a wonder, beautiful sound full and powerful. I opened it and I discovery in four Celestion greenback G12H30 pre-rola very well conserved over 2 small tweeters that feed the trunk superb red. With this box, I can have both a Marshall and a speaker at the original look. Only default: weight, but hey, there are casters.
