Pump Up Your Jams!

The Waves OneKnob Pumper is a simple plug-in that simulates the effect of applying sidechain compression to a track. Dropped into a synth pad's effect chain and synced with a four-on-the-floor kick drum, it adds the instantly recognizable pumping effect that is a hallmark of EDM. But OneKnob Pumper's usefulness doesn't end there. Sound designers and electronic musicians at Sweetwater employ it as a creative tool to add subtle or drastic amplitude modulation on numerous sources — for creating warbly vocals, atmospheric tremolo, undulating bass, and more. Additionally, OneKnob Pumper offers a variable rate control and an offset function for dragging the effect behind the beat. With its single knob design for dialing in the depth of the effect, OneKnob Pumper is a fast and fun way to pump up your tracks!

Waves OneKnob Pumper Features:

  • Easy-to-use single knob design for dialing in the depth of the effect
  • Simulates sidechain compression
  • Create a signature EDM pumping effect instantly
  • Use it as a creative amplitude modulator
  • Syncs to your DAW's tempo map and includes a variable rate control
  • Offset function allows you to drag the effect behind the beat

Rated 5/5

Does not disappoint

Great little plugin - very easy to use - and I can definitely notice a difference in my mixes after throwing this in. As others have stated, more experienced side-chain users might do better with xfer LFO tool or something that gives more precision control, but for someone like myself who is new to using side chain compression, this is extremely practical and works great.
Rated 4.5/5

Pumper is awesome!!!

This plugin was well worth the money for me. Takes just a second to plug it in your track and it syncs to your bpm. Even though side chaining isn't that difficult, it's really easy to dial in that sweet spot in ducking. I caught this one on sale and snagged it. It's great for playing live also. Love my Waves plugins!!!!
Music background: Live and studio musician for 30 years

Since the early days of DAW software, Waves has been a dominating force in music and audio production. For those of us here at Sweetwater who've been recording since the industry switched over to computer-based studios, it's impossible to imagine sessions without L series Ultramaximizers, MaxxBass, and other staples. Since then, we've been impressed every time Waves has brought top producers such as Jack Joseph Puig and Chris Lord-Alge to Sweetwater to show off their next cutting-edge creations, and Waves is constantly adding new and innovative plug-ins to their catalog. And with cool new gear such as their SoundGrid series, Sweetwater engineers have discovered just how easy it is to use Waves plug-ins live.
