Bass

A four-string bass with a deep, plucked-string voice synthesized from noise and feedback. Click anywhere along a string — closer to the body means a higher fret — or play the open strings with the keyboard.

The volume knob on the body adds a two-stage distorted low end. Every note is generated in real time by the Web Audio API.

Open strings

Standard tuning: E A D G

1–4 open strings

Click a string to pluck it, or click along the neck to add frets. Keys 1–4 pluck the open strings. Click the volume knob on the bass — or the Distortion button — for a heavy, fuzzy low end.
