It would be very cool to see some old Laney amps, cabs, and vintage mics, in the Helix world... that might help.
But.... a lot of those old studio recordings used some form of double tracking, some pretty heavy reverb in places (the intro), and tracked through some not-so-close mic techniques... etc, and not to be ignored is that Tony was really unique with playing really light strings and probably specific pickups, and his methods of actually playing with his leather? finger tip replacements and whatever.
It's a bit of a rabbit hole that, and he probably doesn't even know how to recreate 'those tones'.
