Roland TB-303 was the tool used to create the ultimate new dance sound circa 1986-1988, called acid house - and this style's pioneers were among others Phuture Pfantasy Club, Phuture, Dj. Derelict, Adonis. Most of these artists released through Chicago -based Trax Records label. Phuture's Acid Trax is known as the first acid house track.

Originally planned to be used alongside Roland TR-606 drum machine, this little box created some nice basslines but with little creative knob tweaking (one controls it parameters by these knobs) one can easily create this familiar acid-sound. This little box had nice feature; sometimes when one turns it on, there's a random pattern of notes waiting to be played, which is probably how most of the acid tracks were created, since 303 has been known quite difficult to program.
