Overdrive: aim the bite before raising the drive

Keep the foundation, work on the edge

A bass line can have plenty of low-frequency energy yet be difficult to follow. Adding more bass level may only crowd the mix. A controlled distorted component offers another route: give the note extra harmonic information while retaining some original fundamental. Overdrive is useful here because its frequency and width controls act before the distortion stage.

The first example is an original eight-second synthesized bass pattern, not a bass-guitar recording. It contains accented notes among quieter ones. Start with frequency 900 Hz, Width 4, Drive 65%, Tone 60%, Dynamics 50% and Dry/Wet 50%. The blend is intentional: the original bass supplies weight while the processed portion demonstrates the bite.

Temporarily move Dry/Wet to 100% to inspect that processed portion. Sweep the filter centre from about 400 Hz to 1.8 kHz. Follow where the sound becomes thick, nasal or faint, then stop where the note has useful definition. A high centre with a narrow width may receive very little energy from this bass; adding Drive cannot recover material the filter has largely removed.

Width is not a post-distortion treble cut

Width is measured in octaves, although the panel displays a plain number. Smaller values narrow the band sent into the nonlinear core. Try Width 2 against 6 with the centre unchanged. Narrow settings can concentrate a particular bite; broad settings allow more of the note to influence the distortion. At the top of the range, around 9, the implementation switches to an all-pass response rather than continuing to narrow or boost a band.

Return Dry/Wet to 50%, then move it between 25% and 65%. Listen for pitch clarity as well as added rasp. If the lowest note seems to shrink, reduce the blend before boosting the source. The wet path is filtered and the blend changes level as well as character; equal knob positions do not imply equal perceived loudness.

Use Tone after choosing what gets driven

Increase Drive from 40% toward 70% with the filter settled. If the result becomes fizzy, try lowering Tone from 60% to 35%. Tone changes a high shelf at 2 kHz after the core. Its native shelf is referenced to Tone 100%, with lower settings cutting relative to that reference; Tone 50% is not a general-purpose neutral EQ position. Back Drive down if a duller but still flattened sound replaces the original problem.

Let drums test the dynamics decision

This original eight-second drum synthesis alternates a decaying low kick-like tone with a noisy snare-like hit. The 2.2 kHz centre and Width 3 favour the noisy component. Drive 55%, Tone 45% and a 35% wet blend keep the experiment focused on roughening that component rather than replacing the entire rhythm.

Compare Dynamics at 20% and 80%, keeping Drive fixed. Attend to the relationship between the hit and its decay, not just overall level. Dynamics conditions the processing model; it is not a compressor with a visible threshold, ratio or release time. Choose the setting that keeps the rhythmic contrast you need, and lower Drive or the wet blend if the hits become too uniform.

Public Overdrive passes the filtered input through a short, original smoothing filter before its learned distortion core and Tone stage. It retains the model and controls, but does not use the captured input-filter response retained for private reference, so its timbre differs. The wet path still adds about 21.3 ms of fixed delay, with the internal dry path delayed to match. That alignment supports this blend; it does not mean the app compensates every other parallel track.
