No, he did use that mod before he was slaving, again in order to bring volume down.
The issue with those sticks of dynamite was blown OT's.
It was dumped early on.

The pedalboard and effects chain:

Ed used this crappy plywood pedalboard for his effects pedals.
The 2 Maestro Echoplexes were sitting next to the amps on ED's side of the stage, but their footswitches were located next to the plywood board.
The Univox was shelved in a real WWII bomb standing to the right of Ed's cabs.
It was just unbelievable you know, those were really the good 'ol days.
On the board, Ed's guitar would hit the MXR Flanger, then the MXR Phase 90.
From the ouput of the phase 90, a long cable would then reach the 2 echoplexes (wired in series).
After the echoplexes, another long cable would go back to the stage pedalboard to the input of BOX 1, then out to the input of BOX 2.
Yet another long cable would connect the ouput of BOX 2 to a "Y"-type splitter , and then hit the top left inputs of the main plexi and its smallbox backup.
BOX 1 and 2 were loopers for the MXR 6bandEQ 's Ed was using to boost his signal prior to hitting the plexi.
Most of the time, Box2 was not used, but from time to time he would have a second MXR EQ on his board.
The MXR EQ's were replaced by The Boss EQ's in the summer after the japanese leg of the tour.
Btw, Ed was not using a wireless yet in 1978.
The MXR pedals were stock script logo pedals.
In the early 80's, Ed had them overlooked by Jose to reduce unwanted noise (shielding and replacing cheap components with better ones).

The main plexi and his backup were loaded and the line level signal was fed to the univox before it was slaved to the superleads and out to the cabs.
It looks like he's bypassing the Flanger and Phase and going straight into the 1 box where the blue MXR EQ usually goes when it's connected.

WHAT A NEAT GRAPHIC REPRESENTATION !
It is correct, and as you can see, the input of MXR EQ is not connected, hence the unconnected short blue cord (saving batteries).
Ed would connect it for his live guitar solo and certain songs, for example 'I'm the one'.
It was just a matter of how it felt to him on a given day.
The pic was taken in the summer of 1978 and the MXR EQ was gone in favour of The BOSS EQ.
The 2 purple cords are the in's and out's of looper BOX number 1.
Looper box 2 is not in use on that day, that's why we don't see a second Boss EQ in the pic.

"capacitors" & "sticks of dynamite" = the cap for the master volume.

From Jose's old shop. He had it on his bench for years.....A friend bought everything from his shop after he passed. I have other things too...like his old con strobe tuner even some old tapes of music..old tube tester.

However, the box labeled #1, she had two input looks like to me and three outs? Box Label II is not even hooked up??? Anyways thought maybe you could give in detail whats going on in this pic?? Looks like his axe is going straight in to Pedal #1 to me I could be wrong??

He was always going straight into the Flanger, then Phaser, then the Echoplexes.
Those old MXR script logo flangers had both In's and Out's on the right same side of the pedal.

Yes that was for the master volume.
For some reason (I'm not a tech), it would cause OT failure quite often.

Oh that's cool.
I never met him unfortunatly.
Then that "load box" you have should be similar to the ones he made for Ed.
Ever thought of manufacturing it ?

Jose's grounding was the problem I would guess..I have had to fix this stuff when fixing old Jose mods
