The Roland TR-808 drum machine gave birth to 808s, a sort of electronic percussion sample. They have a snappy low end that is easily adjustable to various pitches. The first click and a prolonged deep bass tone are two different aspects of the
808 beat sound. The first click was designed to sound like a real drum beater striking the drum’s skin, while the persistent bass sounds accompanying the click were intended to sound like a decaying thump.
