Hello and welcome back.... The Roland TB-303 was born in 1982 and changed the sound of electronic dance music. The TB (Transistorized Bass) 303 was a bass synthesizer with a built in sequencer. It was released in the western world from japan to replace a bass guitar. It originally failed, selling only 10 thousand units but it resurfaced in the late 80s (Detroit) as a serious acid dance/techno house synth. By changing a series of knobs on the 303 you could get a sticky acid sound that sounds very futuristic.
Bands that have used the TB-303 are Heaven 17, The KLF, Phuture and 808 State and just about any band with the word acid in it :)
HEAVEN 17 - LET ME GO
THE KLF - WHAT TIME IS LOVE
PHUTURE - ACID TRACKS
808 STATE - IN YER FACE
