It's brilliant, it's a masterpiece. If you have an idea of what is going on in the inside, if you look at the circuit diagram, and you see how the unknown Roland engineer was making the best out of super limited technology, it's unbelievable.

It's engineering art, it's so beautifully made.

Its sounds are included with music software and modern drum machines and it has inspired unlicensed recreations. Its particular popularity in hip hop has made it one of the most influential inventions in popular music, comparable to the Fender Stratocaster's impact on rock. The 808 was eventually used on more hit records than any other drum machine. It became a cornerstone of the emerging electronic, dance and hip hop genres, popularized by early hits such as ' Sexual Healing' by Marvin Gaye and ' Planet Rock' by Afrika Bambaataa and the Soulsonic Force. Over the course of the 1980s, the 808 attracted a cult following among underground musicians for its affordability on the used market, ease of use and idiosyncratic sounds, particularly its deep, 'booming' bass drum.

Launched when electronic music had yet to become mainstream, the 808 received mixed reviews for its unrealistic drum sounds and was a commercial failure. Unlike its nearest competitor at the time, the more expensive Linn LM-1, the 808 generates sounds using analog synthesis rather than by playing samples. It was one of the first drum machines to allow users to program rhythms instead of using preset patterns.
