If you're not chasing one specific fix and just want things to sound better, a light touch across all four bands usually beats one big dramatic change.
Try a small boost at 60Hz for warmth, a small cut around 500Hz to reduce boxiness, and a small boost at 8kHz for clarity — all in the 2–4dB range. That gentle shape improves most recordings without drawing attention to itself.
It's easy to keep nudging sliders indefinitely chasing a marginally better sound. Use the Bypass switch periodically to confirm you're still meaningfully improving on the original — once the difference feels small, further tweaking often isn't worth it.
