What have you done to your DOD 250 to make it a boost? I always find the 250 circuit to feel like a very natural extension of the amp. I also like the sound of the vintage flanger, less pronounced, smoother.
I upgraded a few other components, added a toggle switch to switch the input cap between stock (10nF) and 33nF for use with single coils, but the two main changes that help in getting a slightly cleaner (less fuzzy) and louder and more crunchy signal: replace the silicon diodes with green 5mm LEDs and the IC with a TL071.
I wish he would have elaborated on why he didn't think the JBL was involved. Just listening to the Aint Talkin iso clip posted above, there is a snarliness to the mids and a lack of low end that sure sounds like something was between guitar and amp. But I attributed that midrange/low end thing to the JBL, which I have never tried myself.
While simultaneously posting Rockstah modded overly gained clips that sound not as close, but to him sound more true to EVH...??
One can only hope Dave Friedman shoots him down a few times more. ?
