The second bass player is David Goldflies. He played with Dickey Betts and Dan Toler in Great Southern/Dickey solo before the Allmans reformed in seventies. I believe he still has that Series I. He also uses an Alembic preamp (F1-x or F2-B, not sure) and Bag End 15s. I honestly prefer his bass playing over Lamar Williams'. Maybe I just lean more towards the Alembic players.
