MusicTechHelpGuy tackles a common bass problem: notes played higher on the neck often hit louder than open strings, leaving the part uneven before you even touch a fader.
He places the compressor after EQ and switches to the Opto circuit, which reacts more musically to bass frequencies than faster circuit types.
The result tames harsh transients while letting the ring and sustain of each note come through, evening out the performance without squashing its character.
A touch of makeup gain adds back some body and weight, giving the bass a bit more presence in the mix.
