Efektor Custom Bundle - Kuassa

Product Description

Choose Your Rig

Due to high demand, Kuassa have just announced their Efektor Custom Bundle. This bundle enables users to choose any five of Kuassa’s current and future Efektor pedal effect software plugins at a reduced price.

After gaining lots of attention since Kuassa's first release in July 2017, until now the total number of Efektor devices is at 12 devices and counting. Efektor devices are Kuassa's culmination of the latest DSP research made after studying an extensive collection of 100+ electronic schemas of the most sought after guitar effect pedals, comparing them with the actual hardware, then grouping them into distinct categories so that each device can accurately emulate the sound of almost any available guitar effect pedals on the market; Distortions, Modulations, Time Based, Dynamic, Filter, Equalization and Room emulations.

EFEKTOR OD3603 Overdrive

The Warm, Crunchy, Cranked Amp Tone

Back in the early days of electric guitars and amplification, guitar players didn’t care if their guitar sounds were altered to ‘breaking’ by the very limit of their amps. They pushed the gain on their amps for just one thing LOUD. It resulted in crunchy saturated sound, added sustain, raw, but responded very well to the dynamics of the playing. Straight for rock n roll in a box, you may choose from five models of overdrive:

  • Blues Overdrive: Imitates overdriven British amps
  • Boutique Overdrive: A custom made overdrive, sounds fat and dynamic
  • Mad Overdrive: Hard, thick and retains the dynamic of your playing
  • Modern Overdrive: A new model of overdrive that can be pushed into dense distortion
  • Pro Overdrive: Warm and tight, the classic screamer sound
  • Zepp Fuzz: The vintage British rock sound

EFEKTOR DS3603 Distortion

The Red Hot Chilli for Your Tone

There are always demands more 'gain’ - the search for the perfect distortion sound that never ends. DS3603 brings five types of massive amounts of gain for demolition.

DS3603 Distortion clips the input signal by increasing the signal to maximum overload. Adding musical harmonics and overtones while still maintains the characteristics of the original sound, or not. You choose. For heavy metal guitars or abrasive and pounding industrial drums, seek from five types of distortion:

  • Lead Distortion: Ringing mids for screaming leads
  • Heavy Distortion: Penetrates from mild to heavy
  • Metal Distortion: Dark and thick, the solid metal gear
  • Classic Distortion: Singing leads and rockin’ hard
  • Pro Distortion: Fat and sharp edge for your tone


The Good Old Fuzzy Woolly Distortion Box

Probably the most primitive type of distortion device. Instantly recognizable from the woolly, gritty, and compressed ‘artificial’ sound. There are five types of buzzy tone benders on the FZ3603.

Kuassa Efektor is a new line of plug-ins that consists of several of the most requested effect units. The grandfather of ‘artificial’ effect units. Recognizable from its distinct sound, heavily clipped and compressed to the point where the waveform is squared, adding harsh and complex harmonics and in harmonics, almost synth-like. Select from five models of fuzzboxes:

  • Big Fuzz: The gritty and woolly sustaining note
  • Sustainer Fuzz: Blistering rhythm and singing leads
  • Trans Fuzz: The familiar fuzzy transistor sound
  • Vintage Fuzz: Modern recreation of the sound from the 60s
  • Zepp Fuzz: The vintage British rock sound

EFEKTOR CP3603 Compressor

For Firm, Better, Well-Balanced Guitar Tracks

Completing your virtual pedalboard with our Efektor series, now introducing: KUASSA CP3603 Compressor unit. This unit is a result from the endless research of many compressor pedals, a lot of characteristics and finally, we narrowed down everything into one st unit that can represent many other compressor pedals in a straightforward package.

Compressor FX Engine

Will suppress the loudest part of the incoming audio signal, based on the specified threshold. Following the ‘compression, it will increase the softer signal, narrowing the dynamic range thus delivers a more consistent overall level.

Guitar players. Bass players. They are the same. They love long sustaining notes. A Compressor is the one thing that should help with that desire. It is an effect that does not always sound too obvious, but when taken away, it surely will be missed. A compressor will suppress the loudest part of incoming audio signals, based on the specified threshold. Following the ‘compression, it will increase the softer signal, narrowing the dynamic range thus delivers a more consistent overall level. And please take note, although this unit is designed specifically for guitar and bass players, you can also use it on any other instrument as well. Well, why not?

There are three types of compression styles in this unit:

  • VCA: Stands for “Voltage Controlled Amplifier”. It’s fast, modern, and sounds very clean. 
  • FET: Stands for “Field Effect Transistor”. Known for its aggressive behavior and also adds distinct color to the resulting sound. 
  • OPTO: Shorts for “Optical”. It has the slowest reaction but gives more characteristics and tightness to the result.

EFEKTOR CH3604 Chorus

From Classic to Vast Spectrum Chorusing Effect

Recognizable from its doubling effect, this type of effect is known as a standard built-in effect from gears such as the Roland Jazz Chorus amp and also the Roland Juno synthesizer. 

Choose your favorite chorus sound from these three types:

  • Dimension Chorus: Add thickness, 3-dimensional depth, and width from true analog circuit modeling.
  • Ensemble Chorus: A true classic chorusing effect with great tone. soft, deep, and rich.
  • Tribunal Chorus: Big spectrum creates rich soundscapes in stereo. The sounds of multiple modulations combined together.

EFEKTOR FL3606 Flanger

Howling, Swirly, and Flanging Tone

Originated from manipulating tape recorders by slowing down one of its flange (hence the ‘flanger name), this effect creates a swooshing sound dubbed as the ‘jet engine’ effect:

  • Royal Flanger: The “Vintage” Flanging Effect.
  • Jet Flanger: Supersonic Jet Howl or Cool Spacey Stereo Image.
  • Electro Flanger: Darker, Swirly, Chorusy, and Trippy Sound.

EFEKTOR PH3605 Phaser

The Phase Shifter from Outer Space

Full name, Phase Shifter. Typically more subtle than a flanger, but sounds like warblers coming from outer space. Often used on Rhodes electric piano, and of course by guitarists such as Brian May (Queen) and Eddie Van Halen (Van Halen). 

The Efektor PH3605 Phaser provides three types of sound:

  • Phase One: Mild phasing effect, great for a clean tone. Less dramatic sweep.
  • Dual-Phase: Warm and thick phasing sound that sounds great with distorted guitar tones. Great for many instruments such as guitar, bass, keyboards, and vocals.
  • Multi-Phase: More intense effect. Offers more than a standard wobbling effect.

EFEKTOR TR3604 Tremolo

More Waveform!

Probably one of the oldest effects applied to a musical device. This volume modulating effect is known to be equipped on guitar amps such as Fender Twin Reverb or Vox AC3. Classic volume modulation with greater control over tremolo speed and wave shape.

Choose from three types of wave oscillations:

  • Sine Wave
  • Square Wave
  • Triangle/Sawtooth Wave

EFEKTOR WF3607 Wah-Filter

Wa Wa Wacka Wacka Wacka Wa Wa

In the 1920s guitar players were fascinated by the “wa wa wa” sound made by trumpet players by opening and closing their mutes. Its filtering effect alters the resonance of the instrument and it feels to increase the expressiveness of playing.

More than 40 years later, an accidental invention resulted in a device that continues to change the sound of the guitar. This pedal was eventually known as the Cry Baby*. Next, in the 1970s, an aborted synthesizer project resulted in a similar “wah-wah” effect, which was later known as Mu-Tron* III envelope filter. These two devices revolutionized almost every genre of music as we know it today

Select from 6 types filter modes:

  • CB: Dunlop™ Cry Baby*
  • VG: Vox™ Grey Wah*
  • AX: Vertex™ Axis Wah*
  • MuLP: Mu-Tron™ Low Pass*
  • MuBP: Mu-Tron™ Band Pass*
  • MuHP: Mu-Tron™ High Pass*

EFEKTOR DL3606 Delay



It’s probably one of the most essential effects in audio effect processing, even before it was widely used in music. It all started in the 1940s, where studio engineers utilized multiple tape machines to create repeats of a signal for creative uses. Along with the advancement of technology, this particular kind of effect is still developed continuously with more features, new sounds, and modern routing possibilities. On the other hand, many players still seek classic delay sounds that can be heard on a great number of timeless records.

In the path to complete the line of Efektor pedal effects software, Kuassa presents the Efektor DL3606 Delay. Efektor DL3606 brings the five most desirable types of delay effect audio plugins to your DAW, complete with modulation parameters to add life and movement to the repeats or echoes.

Starting from utilizing multiple tape recorders, oil can electrostatic units, portable tape delay machines, to rack units and compact delay pedals; Kuassa Efektor DL3606 Delay provides 5 types of delay pedal effects software at your disposal:

  • Digital: Clean and clear, with a wide frequency range.
  • Analog: Dark and mushy, inspired by the bucket brigade delay pedals
  • Lo-Fi: Grainy and dirty, lower bitrate with a reduced frequency range
  • Tape: Simulated the warm and lush sound of vintage tape units
  • Reverse: Repeats the signal backward for ethereal and ambient effect

EFEKTOR RV3604 Reverb

Efektor RV3604 Reverb comes with 5 different types of versatile reverbs, found on guitar pedals used on the greatest recordings of the century. RV3604 uses simpler controls so you can create roomy ambience, surfboard crashing waves, far-reaching space, sun-over-the-clouds moments and holy-lights-from-the-sky epicness.

Reverb is the most commonly used effect on every source of every recording. It can be found anywhere from small practice amps to big touring amps. It can also be found on stompbox pedal effects to large studio rack units. Its usage can be somewhat tricky, but reverb is often the fine border between a professional's recording and a beginner’s work. Reverb is a powerful tool to add depth, distance and also to build emotion for the listener. It gives ambience, creates space, and produces a sense of three-dimensional to the original sound. 

Taken the algorithms from the sounds of natural spaces to artificially created electrical and mechanical devices, Kuassa Efektor RV3604 Reverb provides five types of Reverb to enhance your recordings:

  • Room: Tight and fat roomy sound.
  • Hall: Big and wide concert space.
  • Plate: Simulated vibrating metal plate. Grainy and unique because the low frequency propagates slower than the high freq.
  • Spring: Simulating mechanical springs commonly found on guitar amps.
  • Shimmer: Haunting and atmospheric reverb, created by pitch-shifting the reverb tails.
