I've played a number of O size Suzukis with slotted heads. These were great guitars for the money. I've seen Joe Hall playing one at festivals. I can't remember if they had 12 or 14 fret necks, but otherwise, they're a lot like the pre-war Martin O-18s. I also have a friend who owns a Suzuki dreadnought and I sometimes forget I'm not playing my '62 D-21 when I borrow it.

For the money, 2-3 hundred dollars, these are great guitars.
