at the tab archive it's writen down as "b7". thats one of the most beautiful parts in stella blue. thats another way:
i took it directly from the grateful dead movie, so it should be correct ( because you can see him playing it)
(/) Slide Up () Slide Down (h) Hammer On (p) Pull Off (b) Bend (r) Release (v) Vibrato
