Dynamic Distortion / Effects / Console 1 Ready

Harmonics Analog Saturation Processor

USD 149


Did you ever try to give a track attitude by adding distortion, but then wind up with a washed out, lifeless sound instead? Harmonics, with its never-before-heard approach to dynamics in distortion, is the answer.

The only plug-in to track incoming dynamics and allow the user total control  over their application in the output signal, Harmonics is a giant leap forward for searing, roaring, face-melting sounds everywhere.


Truly varied sounds

5 utterly distinct distortion models, each based on a different tasty analog distortion process. Tubes, transformers, zingy circuitry of all kinds.


Revolutionary 'Dynamic Transient Control' technology

Harmonics listens to the dynamics of the input signal, in order to maintain, increase, or control the range of the distorted signal in a way you need to hear to believe.


Total control

Low and high cut filters, parallel mix control, and THD (total harmonic drive) metering allow you to define the perfect sound for your track every time.


"...the perfect all in one plug-in for adding crunch to drums, fuzz to bass and edge to a lead vocal..."

Joe Chiccarelli
Mixer/Engineer/Producer for Beck, U2, The Strokes, Elton John, etc.

Distortion dilemma

Guitars, vocals, drums, bass, even synths often need some extra grunt to push them over the edge, but distortion can destroy dynamics and cause more problems than it solves. Too little and your sound doesn’t cut through and fill its space. Too much and you lose the light and shade, the attack and decay. Transients blend into tails, and detail and definition go out the window.

Such is the tragic plight of the musician or mix engineer working with distortion. With Harmonics, the struggle is over!

Light it up

With Harmonics, you get much more than just five awesome-sounding analog distortion models. You also get a revolutionary new approach to handling dynamics during the process of distorting the sound. The input signal is listened to and analysed by the plug-in, allowing the dynamics and detail to be preserved and enhanced even after heavy distortion is applied.

Add to that the fact that Harmonics has five totally different-sounding component-modelled distortion styles, high and low cut filters, a parallel mix knob and more, and you end up with a very powerful secret weapon indeed.

"Fantastic plug-in — super versatile and musical. Love the thickness it creates…"
