Ken, I just played in a Strauss Waltz Orch on New Year'sDay w/ Dennis Masuzzo (the big 5ths tuning advocate) in the section and he had a beautiful cornerless Italian that is supposedly from 1833 by Vincenzo Lucarini. I wish I had taken a picture of it. It has a similar shape to Mr. Grillo's bass and had a very fine sound and spread throughout the room. My Prescott held it's own
next to it along w/ a really nice old Italian violin cornered bass that was from the late 1700's.
