303_LINE History
The history of the Roland TB-303
Roland sold it as a practice tool for guitarists in 1981. It flopped, turned up in pawn shops, and then Chicago found the resonance knob.
Timeline
- 1981 — (some sources say 1982) Roland releases the TB-303 Bass Line as a solo-practice companion for guitarists, designed to play bass lines under a player. A matching drum machine, the TR-606, came out around the same time.
- 1983–84 — The TB-303 is discontinued after a short production run. It had sold poorly, and used units flood secondhand shops for pocket change.
- 1985–87 — Chicago producers, including the group Phuture, buy cheap 303s and discover that pushing resonance and envelope modulation to the edge, then changing the pattern while it plays, produces a screaming, liquid tone nobody at Roland intended.
- 1987 — "Acid Tracks" by Phuture. The genre gets its name from the sound of the machine itself.
- 1988–92 — Acid house spreads across the UK and Europe. Original 303s, once worthless, start climbing in price.
- 2000s–today — A clone economy grows: hardware and software recreations chasing the same filter and sequencer, because the demand never stopped.
Why it failed first
The TB-303 was meant to sound like a bass guitar so that a lone guitarist could practice over it. It does not. Its sawtooth or square oscillator through a resonant low-pass filter sounds like nothing else, and its sequencer was awkward to program. Musicians who wanted a believable bass were disappointed, and sales were weak.
How it became the sound of acid
Young producers with little money could buy a 303 for next to nothing. They did not care that it did not sound like a bass guitar, and they used the controls the manual treated as footnotes. Turning the resonance up, sweeping the cutoff by hand and pushing the envelope amount high turned a plain line into a squelching, shifting voice. Accent and slide, two features meant to add a human feel, gave the rhythm its bounce and the notes their glide.
The machine today
Original units are now collectors' items. Current asking prices are on the TB-303 price page, and if you want the sound without the price, see clones and reissues. You can also try an acid line right now in the free emulator.
"It was supposed to sound like a bass guitar. It sounds nothing like a bass guitar. That's the whole point."
