Jose did different mods to suit the occasion.
The zener diode master was only one of them and it was copied by Peavey for their VTM amps.
The Jose zener diode master mod also included an extra amp stage and was towards the higher gain end.
Jose also often used the front panel input sockets for new knobs and EVH's main amp isn't like that at all and neither are his other old Marshall's.
All of that points to Jose making it up and adapting as he went along to suit what the player wanted IMO and I don't know how much of it relates to EVH or if any of it relates to EVH.
I don't know about an extra stage automatically being included with a Jose master, there was a HG and a LG Jose...
The Jose ones I've seen are high gain extra stage zener master's.
I'm not sure if the low gain zeners are Jose or from someone else doing their own variation.
There are/were so many marketing shills into EVH stuff selling their magic potions to EVH fanboys, that believing them is a leap of faith.
Of course EVH was BSing a fair bit as well and some followed his BS.
The only accounts I would tend to believe are the John Suhr one and the Dave Friedman one and one other one that I can't remember at the moment (Steve Fryette VHT) and they all say basically the same things.
John Suhr had EVH's main amp before the rewiring was done by that Dutch dude, and so John Suhr could see the original solder points and what solder points were original and what solder points weren't and he could see the circuit values.
John Suhr's account (from what I can remember) is that the preamp solder points were original (no extra stage mod) except for a fat cap on V2 and the solder points up near the phase inverter could have had something like a master volume connected to them.
Something like a zener master is fine as long as it goes into a good sounding amp in the first place, and the zener voltage can make a big difference.
