The origins of the Demanufacture Marshall are hard to pin down. Some say its a :
Metalhead mod (by a Russian dude named Ellan)
Here's the info that I've got on Elan:
Metalhead Mods:
Elan Memran was an EE for Yamaha at the time in LA. He and his brother had Metalhead studios on Cahuenga Blvd but he first started modding Marshalls out of his garage in Burbank for bands like Skid Row, Fear Factory, Assailant, and WASP. The Metalhead Modded Marshalls were popular in Hollywood during the 80's.
The extra jack beside the noise gate pot is a footswitch jack for switching the preamp mod in and out. This was the old-school way of getting a "clean" channel on a modded Marshall w/o building a separate preamp channel. The pull knob on the bass control is a bass boost mod. The 2 extra knobs by the input jack was a noise gate and extra gain controls. Both are push pull as well. Some amps also had a mid boost mod, activated by pulling the mid control knob similar to the bass boost. The loops are tube buffered.
