Very helpful Lowend and Ilan, I see it now. Which reminds me: The TBird Studios had better upper fretboard access, doodling in A between the 17th and 19th fret was no issue, with a real TBird you can't sensibly do that beyond G (15th and 17th fret). That was always one of the good things about the Studio (soundwise it was a Victory/TBird hybrid). Likewise, the set neck Studios did not neck-dive, but were stable and heavy with their thick body (the neck-thru TBird is in contrast to his unjustified image - due to his size - as a heavy bass not heavy at all).
"Pulling out the neck" is a small, nuanced change, but one that makes sense. Could well imagine that Gene had his
hand paws in that because he likes to slide notes all the way up and down, he needs high register access with his playing style.
And if you move up the neck in its extrusion from the body, moving the pups makes sense too. Gene is not a
"treble pup squeezed to the bridge"-bony-sound fan, his own Punishers don't even have a bridge pup (in contrast to the ones you could buy) because he never uses one. If you look at the G2 pup positioning in relation to the pg, you can see that they have moved the treble pup a complete and the bass pup half a pup-width forward.
