...all of us here seen many of the great bassists of our time live in large venues and to be honest it hasnt mattered much what bass they were playing
Pardon my beg to differment, John, but I can definitely say that Phil Lesh's tone varied vastly between the osage orange Alembic, the Irwin and the Modulases (Moduli?) (and, to my ear, each change was not just a change, but a signifigant step down in tone. Phil, it would seem, disagrees)
Got to agree on Squire, though - the one time I saw them, he switched constantly & I heard no change; I think it was mostly just for the spectacle of the basses coming up out of the floor.
