Hear it before you buy it

Clean in.
Shifted out.

Choose a source, switch from clean to shifted, and hear exactly what each gear gives the track. Every pair is level-matched from the same performance.

SELECT A SOURCEREVERB / CANYON

VOCAL / CLEAN

Tap A/B at any point to compare the exact same moment. Play runs the selected side only.

The gearbox

One move.
Five directions.

This is the part that makes FIZZFUEL feel different: effects are not hidden in menus. Pick a gear, pick its personality, then shape it with the clutch and controls.

Gear 01

Drive

Take a vocal, drum, or instrument from a little more expensive to properly redlined. Drive has five usable characters, so you can find the attitude before you touch another plugin.

TapeTubeConsoleClipFuzz

Know every control

No menu diving.
Just movement.

The controls are deliberately few because each one is meant to matter. The final build will pair these with close-up interface callouts.

01 / SHIFTER

Choose the effect

Throw the stick into Drive, Reverb, Delay, Pitch, Filter, or R for a clean reference. Every change crossfades smoothly.

02 / STYLE

Choose its character

Each gear has distinct styles: Tape or Fuzz, Room or Canyon, Slap or Long. The effect stays familiar; the personality changes.

03 / CLUTCH + MIX

Choose how far it goes

The clutch pushes intensity. Shape controls refine the selected gear, and Mix lets you blend the move back into the original signal.

Built for the session

Make the next
idea move.

FIZZFUEL is not a pile of effects. It is a quick decision-making tool for moments that need energy, space, or a hard left turn.

VOCALS

Make a line feel alive.

Warm a lead with Drive, pull it forward with a short Delay, or turn the last word into a moment with Pitch.

DRUMS

Make impact feel intentional.

Use Console or Clip for urgency, then switch to Filter or Reverb when the arrangement needs a new scene.

TRANSITIONS

Make the switch happen.

Throw from a clean reference into a shimmer, a resonant sweep, or a long repeat without breaking the creative flow.

Frequently Asked

FIZZFUEL is a multi-effect plugin built around a manual gearshift. You throw the stick into a gear to pick Drive, Reverb, Delay, Pitch, Filter, or R for a clean reference, then shape it with the clutch (intensity) and a style selector. It started life as a saturation gearbox and grew into a full effects rack.

Throw the shifter into the gear you want, exactly like a real gearbox. Each of the six positions is a different effect, and switching crossfades smoothly so there are no clicks — reverb and delay tails ring out as you change gears.

Drive (Tape/Tube/Console/Clip/Fuzz), Reverb (Room/Hall/Plate/Canyon), Delay (Slap/1-8/Dotted/Long), Pitch (-Oct/+5th/Detune/Shimmer), and Filter (Telephone/LP Sweep/Tilt/Reso) — over twenty styles in all, plus a clean A/B gear.

Yes. The Delay gear locks to your DAW's tempo — slap, eighth, dotted-eighth, and long divisions — with filtered, self-oscillating feedback on the clutch.

FIZZFUEL is available as VST3, AU, and AAX on macOS (Intel + Apple Silicon, universal, Pro Tools–signed), and as VST3 on Windows (64-bit) with an easy auto-installer.

Up to 3 machines with one license. To move an activation, deactivate on the old machine and activate on the new one.
