A pure sine wave plus EQ and light reverb is sufficient to build a controlled sub-bass patch

The foundational deep dubstep sub-bass patch starts with a single oscillator set to a sine wave — the purest waveform, containing only the fundamental frequency with no harmonics. From there, EQ shapes the frequency contour (cutting unwanted low frequencies below ~40 Hz, shaping the attack), and a small amount of reverb adds spatial presence without adding harmonic content. No second oscillator, no distortion, no complex modulation. The discipline forces note choice and pitch movement to carry all musical expression. The ‘biting point’ metaphor describes the moment where the level is high enough to feel present but not so high it distorts or overwhelms.

Examples

In a synthesizer (e.g. Reason Subtractor, or any synth with a sine oscillator): set OSC1 to sine, all other oscillators off. Add a high-pass filter around 30–40 Hz to remove subsonic rumble. Apply a short reverb (~0.5–1s, low mix). Adjust output level until the bass sits — audible and felt without masking other elements.

Assessment

Build a four-bar bassline using only a sine oscillator, HPF, and reverb. Then add a second oscillator (square or saw) and compare the two versions on both headphones and a subwoofer speaker. Describe the spectral and perceptual differences and when each approach is appropriate.
