I went to see Ozzfest on the 6th and it was bitchin.I was on the lawn and didn't get a good look at the stage and I couldn't tell how Geezer was playing. Does he play chords live? Also how can I get his tone?
hey. i saw black sabbath on the 20th of june this year in Vienna/Austria (support: Velvet Revolver & Black Label Society).
I was in the 5th row, in front of geezer.
His playing and his sound was amazing.
to your question: I didn't see him playing chords.
He played nearly everything with finger but he took a pick for the last part of Iron Man and for Children of the Grave.
If you're looking for his tone: Now he plays a Lakland bass through a SVT II and a lot of different Ampeg cabs.
