Tweed,
Betts says "JBL Lansing 120's" is his current speaker type.

I spent 3 hours with Twiggs, that Sunday morning after a Dregs show in 76. I was 17. Twiggs woke Steve up and ask him to hand him "The Guitar". I have 3 pics of me and Duane's LP 3. One is me playing Am9 no root (liz chord) and pointing to the scratch that identifies the instrument, Two is me playing Em9 representing Duane's' gift of jazz us, and the third is me and Twiggs head bowed over the guitar.
Translation and my memory could serve as deficiencies here but I did have a player friend/Duane Freak with me and I should call him to confirm the JBL model #. He ask the question and Twigg's responded "They both use JBL XXXX but Duane removed the backs." I knew my friend Marc would remember the model #.
I plowed forward with the questions. Did he use a Fuzz? "He had a few pedals but his main source of distortion was the amp, it was modified by a guy in Atlanta" Who "I don't know Duane had it done." Do you know the name of the shop
No...someplace in Atlanta (be cool chuck). When you say modified you mean master volume "They did a master volume, but they did some other stuff too." Duane's distortion sounds like an emulation of Coltrane's sax, a lot more distorted than just a master volume, do you think the rest of the distortion came from the pedal "No...the distortion mostly came from the amp...he just like to play with the pedals...I didn't think they made that much of a difference...sometimes he didn't even use them."
I don't believe I could recall that 2 minutes that well, I couldn't even repeat that verbally 2 minutes from now, but that's what was said among 3 hours of slam packed AAB trivia.
It took me 2 1/2 hours to lead up to it. When I first jumped up on the running board of the truck I said "Do you really have Duane's guitar and he just stared at me an didn't respond. So I proceeded to explain to him why it was important to me to see it for the next hour and he listened the only thing he said is I got to get something to eat and would you like an RC (cola).
Then he opened up filling in the gaps of what I didn't know, even answering questions I'd ask that he hadn't answered in the order I had ask them.
He talked steady that hour, he explained how he was the second member to join the Duane Allman Band (this was the name of the band as Phil Waldron had been instructed to draw the contract an wasn't changed till Duane's burial a year after his death).
Tweed, You are right, the type head is sorta irrelevant, but not just what we want to believe, but cause the schematic's tell us so, the real question here is what value cathode caps were used in the mod (if it was indeed a four gain mod) because that has 98% effect of the tone.
I do realize you talking about a mid pass to ground and that notch is more significant than a mere 2%, Tweed Dude, I don't know, I gave up, when that filter cap under the ckt board on my JMP (MV and 4 gain mods, and 6 stabs at cathode caps) went, I gave up.
I had gotten as close as Blue Sky and the Duane Fillmore prominent lower octave and other harmonic's had to be the reflection off the brick wall coming from the open back cabinets.
All those years I used open backs I had to be 7 inches off the wall, I was convinced this was Duane's placement on the Fillmore album.
