DI
The raw instrument. Shape it your way.
DI
The raw sound of the instrument, captured directly via high-end, studio-grade recording hardware. Process as you would any other bass for ultimate flexibility.
Clean
The iconic Z3X piano-esque tone.
Clean
The Jacob Umansky tone you know and love — from his playthroughs on Instagram and his work across assorted albums. The unmistakable Z3X piano-esque tone, with depth and clarity that you won't believe can coexist in a single voice.
Grit
Like Clean, but extra.
Grit
Maintains the distinctive spectral balance that defines Jacob's sound while increasing the gain range — so you can really make the bass spank.
Heavy
Fuzzy, mid-heavy auxiliary tone.
Heavy
Based on Jacob's studio tones — this fuzzy, mid-heavy sound replicates an auxiliary tone Jacob uses to create interesting textures in certain parts of his music.
truBass
The engine behind every SubMission Audio virtual instrument.
truBass is our proprietary sampling and scripting engine built specifically for bass instruments. It's why our basses respond like real instruments instead of static sample libraries — every note is shaped by the context around it.
truSlides
Slide from any note to any other note on the virtual fretboard, at any speed. No pre-baked transitions — every slide is generated in real time.
Multi-sampled Fretboard
Every fret position across the entire instrument has been individually sampled. Notes are performed where a real bassist would play them.
Intelligent Picking
Tempo-synced alternate picking with deep round robin. No repeated samples, no matter how fast you write.
Humanize
Subtle natural variation in timing, dynamics, and tone colour. Dial it up for organic feel, or turn it off for machine-tight precision.
DOOM Mode
Collapses the round robin to the most powerful samples. Less variation, more impact — for when every hit needs to land identically.
Position & Force String
Choose where on the fretboard each note is played, and lock notes to specific strings for total tonal control.
