# Roland TB-303
“The Roland TB-303 Bass Line is a synthesizer with built-in sequencer manufactured by the Roland corporation from 1982 to 1984 that had a defining role in the development of contemporary electronic music.
The TB-303 (named for “Transistor Bass”) was originally marketed to guitarists for bass accompaniment while practicing alone. Production lasted approximately 18 months, resulting in only 10,000 units. It was not until the mid- to late-1980s that DJs and electronic musicians in Chicago found a use for the machine in the context of the newly developing house music genre.
I am selling this unit for a friend. He is the original owner. It has been used very sparingly over the years and works perfectly. If you have any questions or would like more pictures please let me know and will be happy to assist you.” Link
