# Distortion *** ### Overview The **Distortion** effect is an analog-inspired harmonic processor that can produce everything from warm saturation to broken tube-style distortion. It also includes filtering and tone controls for precise control of the effect’s color and frequency range.
*** ### 1. Effect Dropdown The **Effect Dropdown** lets you remove or swap the effect and load or save sub-presets. See [**Shared Settings**](https://manual.minimal.audio/evoke-manual/effects-rack/shared-settings) for dropdown options and detailed descriptions. ### 2. Filter Controls These controls affect the variable-width band-pass filter placed before the distortion stage. Use them to focus on specific frequencies, reduce low end, or produce warmer effects. These settings can also be adjusted by switching the **Display Tabs** to reveal the draggable **Filter Display**. **Filter Frequency.** Sets the center frequency of the band-pass filter where the distortion is most pronounced. **Filter Width.** Adjusts the bandwidth around the center. Narrow settings isolate the distortion to a small band; wider settings let more of the original signal through, producing more harmonic content. ### 3. Distortion Display The **Distortion Display** visualizes the distortion’s response in real time as you adjust parameters. Switch the **Display Tabs** to reveal the **Filter Display**, which provides a draggable filter response for adjusting the distortion’s filter settings. ### 4. Distortion Controls **Drive.** Adjusts the amount of gain applied before distortion. Lower values produce more subtle saturation, while higher values produce more intense distortion. **Drive** also interacts with both **Crush** and **Bias** in interesting ways. **Crush.** Introduces additional nonlinear processing that can cause dropouts and additional compression. Higher settings can produce unpredictable effects, especially when combined with higher **Drive** and **Bias**. **Bias.** Applies asymmetry to the distortion curve, adding more even-order harmonics similar to analog tubes. Ideal for warmer saturation at lower **Drive** settings or overdriven-tube behavior at higher **Drive** settings. **Tone.** Tilts the frequency balance toward higher or lower frequencies to adjust the harmonic balance and color of the distortion. ### 5. Mix Controls **In.** Sets the level of the wet signal path before processing. Use it to drive the distortion harder or softer. **Out.** Sets the final level after processing and dry/wet mixing. Use for additional gain compensation if needed. **Mix.** Blends the unprocessed (dry) and processed (wet) signals. Use for parallel distortion effects.
