Apply a 11 dB low-shelf bass preset, then fine-tune the frequency and intensity. The heavy preset starts at 11 dB around 80 Hz. Compare at similar listening levels; additional bass needs output headroom and cannot restore missing low frequencies.

Create a strong low shelf

Eleven decibels gives the heavy preset substantial low-frequency emphasis. Treat it as a creative sound change; applying it to a dense master can substantially change the apparent balance of the song.

Inspect kick sustain

A boosted kick can linger perceptually and overlap the next bass note. Choose a lower shelf frequency or reduce intensity when rhythmic definition becomes less clear.

Watch limiter activity

The live dynamics stage restrains large monitoring peaks. If every drum hit seems to pull the rest of the mix down, lower gain or trim and compare again at a consistent headphone volume.

Respect source limitations

Bass enhancement cannot reconstruct a fundamental removed by an earlier high-pass filter. It amplifies low-frequency material that exists, including handling noise, mains hum or other unwanted components.
