Focus or Sub Anchor: harmonics or more low end?
Focus moves Lava’s added harmonics between low weight and upper presence. Sub Anchor adds more of the low end that’s already in your bass. It doesn’t create a sub-octave. Pick Focus when the bass is hard to hear, Sub Anchor when it needs more weight.
If the bass is hard to hear but the mix already has plenty of low end, more Sub Anchor usually makes it worse. Try Focus first, and listen with the kick.
For S9 Lava 0.1.3.

Step by step
Listen in context
Play the bass with the kick and main parts. Does it need clarity or weight?
Try Focus
Move Focus with Sub Anchor left alone. Listen to where the added character sits.
Try a little Sub Anchor
Go back to your starting point and add a little Sub Anchor. The added bass is centred in the stereo image. Watch your meters.
Leave headroom
Lower Output or Sub Anchor if the next plug-in is being hit too hard.
Good to know
Check high and low notes
Play the lowest and highest notes of the part. A setting that works on one long note may need less Sub Anchor elsewhere.
It can’t add missing notes
Sub Anchor boosts low end that’s already there. If the note you need isn’t in the source, it can’t create it.
