The arguably most famous Hammond organ model, built from January 1955 through 1974.
This one pretty much defines the feature set of a Hammond:
Variations:
- A-100 etc. -- home organs, console style, with built-in amp and speakers
- B3000 -- a 'portable' model (119.3 kg)
- C-3 -- a B-3 in a church model case
- C-3G -- same as C-3, with a built-in speaker
- New B3 -- 2002 remake with sample-based tone generation
- XB-3, XB-5 -- earlier digital B-3 look/soundalikes
