The Volca Bass is an analogue bass synthesizer manufactured by the Japanese music technology company Korg.

[2] The design of the Volca bass has drawn comparisons not only to Korg's Electribe series[3] but also to Roland's TB-303 bass synthesiser.

[7] The Volca Bass follows the standard architecture of a subtractive synthesiser: it produces sound using three voltage-controlled oscillators (VCO),[8] a resonant low-pass voltage-controlled filter (VCF)[3] and a voltage-controlled amplifier (VCA).

The VCOs can be individually switched between sawtooth or square waveforms.

[2][4][9][5] Modulation is supplied by an ADR envelope generator (EG) with switchable sustain[3] and a low-frequency oscillator (LFO) with square and triangle waveforms capable of reaching audio-rate modulation.
