The 303 Acid Bassline is one of dance music’s most iconic and instantly recognisable sounds.

​

But if you're working in Ableton, finding a decent stock preset that captures that raw, squelchy vibe can be a nightmare.

​

So we went ahead and built one for you — a free, ready-to-use preset that nails the acid sound straight out the box. No third-party plugins needed. Just drop it into your project and get jamming.
