The guitar is tuned a half-step down (Eb Ab Db Gb Bb Eb) in the recording, so the guitarist treated the jam session like the blues in A:

The bass is tuned in standard tuning (E A D G), so the bass player treated the jam (fingering-wise) like it was in Ab - which it was.

Be sure to play with that swing feel!
