Yes I know them. I used to have a

Giannini Craviola

way back when and liked it very much. The very unusual body shape allowed good access to the higher frets and the sound was chunky and good. The only other person I've seen playing one was Linda Perry (once of 4 Non-Blondes, now a successful rock/pop producer, e.g. Pink et al).

Brings back good memories!

Peace
