Push & Pull Direction
A new direction switch sits right by the knob. Push rests low and lifts the level on transients for classic upward pump. Pull rests hot and ducks down for a tighter, more controlled feel. Switching between them stays level matched.
Boost
A curve only boost. The same PUMP setting reaches a hotter, denser curve, lifting the ceiling for more drive while leaving the pump depth exactly where you set it.
Level Matched Parallel Mix
MIX is now a true parallel blend that stays level matched at any INPUT drive, so wet and dry sit together honestly no matter how hard you push.
Smoother Response
Refined Fat mode ballistics, a Delta listen that stays matched even with INPUT cranked, and gentler handling of fast knob moves for a more natural feel.
One Knob, Total Control
The PUMP knob drives the entire effect from subtle glue to maximum density. Even at low settings the 4D Modulation system is shaping the signal in time with the music, so the knob mostly controls how visible that motion is.
4D Modulation Engine
Under the hood, four dimensions of the incoming audio are analysed continuously, telling Big Pump how to react. Kicks land harder, vocals push forward, and the effect tracks what the music is actually doing.
Four Mode Personalities
Fat is heavy and low frequency driven. Smooth is slow and glued. Tight is fast and reactive to transients. Open is airy and driven by mids and highs. Each one has its own sound and reaction style.
Push & Pull Direction
Set the pump's direction by the knob. Push rests low and lifts the level on transients. Pull rests hot and ducks down for a tighter, controlled feel. Switching stays level matched, so you can audition both honestly.
Boost
A curve only boost that reaches a hotter, denser curve at the same PUMP setting. It lifts the ceiling for extra drive and density while leaving the pump depth untouched.
Modern & Vintage Character
Modern gives clean odd harmonic saturation for a modern flavour. Vintage adds asymmetric drive on top for even harmonic, tube style warmth. A second saturation layer adds extra transformer style colour on top.
Width, Delta & Oversampling
Width drives the sides harder than the center for glued stereo. Delta solos exactly what Big Pump is adding. Oversampling runs from 2x up to 16x for clean top end when you push hard. Auto Gain keeps your A/Bs honest.

How it works
Three steps to a bigger sound
Pick a mode
Drop Big Pump on a track or bus and choose Fat, Smooth, Tight, or Open to match your material. Each mode tells the engine what to listen for.
Turn it up
Push the PUMP knob until it feels right. The 4D Modulation system shapes the signal in time with the music, so the effect follows the performance.
Dial in the details
Add Width for glued stereo, flip to Vintage for warmth or switch to Pull for a tighter feel, and use Delta to hear exactly what you are adding. Auto Gain keeps the level matched.
