Lee Jackson "Metaltronics" modified 1979 Marshall 50w 1987. This amp is in superb condition given its age. I acquired it from a recording studio in LA, which pampered this amp. I was told Howard Leese from HEART was one of the last people to record with this amp, but unfortunately there is no written documentation to corroborate this story.

The amp has Lee Jackson's added 12ax7 gain stage, Mid Frequency selector switch, added master volume and push-pull Volume and attenuator on the back of the amp. The pictures clearly show the condition of the amp. The mods are unmolested, components look clean/good and the amp is nice and healthy. Here's an opportunity to score an original vintage clean Lee Jackson "Metaltronics" modified Marshall.
