F9 Impact Bass for Serum 2

US Punchy bass presets without sub sonic overload 01/06/26

James Wiltshire from F9 Audio has just released Impact Bass for Serum 2, addressing some of the issues with Bass Presets which are over loading the sub bass, meaning a much weaker bass signal. Many warping, overdrive and distortion methods employed in preset production have been known to add in unwanted sound - and this collection is designed to circumnavigate and resolve these issues.

Stop fighting your low end and learn why most Serum bass presets are destroying your mix headroom and how to fix your sub-bass for professional results. If you've ever struggled with a muddy mix, the secret might be the '10Hz Monster' hiding inside your wavetable synthesis patches. In this video, we dive deep into the technical flaws of modern sound design--from invisible infrasound buildup to momentary DC offsets caused by zero-millisecond VCA envelopes. We explore how excessive filter overdrive and unmonitored sub-oscillators create subsonic energy that eats your headroom without adding audible weight.
