The Roland TB-303 Bass Line is a bass synthesizer released by Roland Corporation in 1981. Designed to simulate bass guitars, it was a commercial failure and was discontinued in 1984. However, cheap second-hand units were adopted by electronic musicians, and its "squelching" or "chirping" sound became a foundation of electronic dance music such as acid house, Chicago house and techno.

Design and features

The TB-303 was designed by Tadao Kikumoto, who also designed the Roland TR-909 drum machine.[1] It was marketed as a "computerised bass machine" to replace the bass guitar;[2] however, according to Forbes, it instead produces a "squelchy tone more reminiscent of a psychedelic mouth harp than a stringed instrument".[3]

The TB-303 has a single oscillator, which produces either a "buzzy" sawtooth wave or a "hollow-sounding" square wave.[3] This is fed into a 24dB[4]low-pass filter, which is manipulated by an envelope generator.[2] The user programs notes and slides using a basic sequencer.[3]

Impact and legacy

The 303's unrealistic sound made it unpopular with its target audience, those who wanted to replace bass guitars. It was discontinued in 1984,[5] and Roland sold off remaining units cheaply.[3]

Chicago group Phuture bought a cheap 303 and began experimenting.[3][4] By manipulating the synthesizer as it played, they created a unique "squelching, resonant and liquid sound".[3] This became the foundation of "Acid Tracks", which was released in 1987 and created the acid genre.[3] Acid, with the 303 as a staple sound, became popular worldwide, particularly as part of the UK's emerging rave culture known as the second summer of love.[3][4] "Rip It Up", by the Scottish post-punk band Orange Juice, which reached #8 in the UK singles chart in February 1983, was the first UK top 10 hit to feature the 303.[6]

Another early use of a TB-303 (in conjunction with a TR-808 drum machine) is Indian musician Charanjit Singh's 1982 album Synthesizing: Ten Ragas to a Disco Beat. It remained obscure until the early 21st century, and is now recognized as a precursor to acid.[7]

In the late 1980s and early 1990s, as new acid styles emerged, the TB-303 was often overdriven, producing a harsher sound, such as on Hardfloor's 1992 EP "Acperience" and Interlect 3000's 1993 EP "Volcano".[8] In other instances the TB-303 was distorted and processed, such as on Josh Wink's 1995 hit "Higher State of Consciousness".[4][9]

As only 10,000 units were manufactured, the popularity of acid dramatically rose the price of used 303 units.[3] According to the Guardian, as of 2014, units sold for over £1,000.[10] In 2011, the Guardian listed the release of the TB-303 as one of the 50 key events in the history of dance music.[5]
