Was listening to Right Off on A Tribute to Jack Johnson , Miles Davis & John McLaughlin and listening to McLaughlin and kept reminding me of Weir with his rhythm style, I could imagine Weir playing rhythm on that, I know the Ibanez 2680 was modeled after Mclaughlins double neck but hadn't heard if Weir was otherwise a big McLaughlin fan or not, also that tone he has on that would be a killer Weir type tone .
Slightly off topic, however, Bitches Brew always reminded me of the Dead.
