Kuassa Pedal/effect plugins Reviews

Kuassa Efektor pedals

The Kuassa Efektor range offers a huge selection of tones. Here is our reviews of the pedal range.

Kuassa’s Efektor series of pedal plugins provides a ton of options for guitarists, bass players, keyboard players and more. On top of that, every one of these plugins is basically a pedal suite with multiple offerings inside. The GUIs across the entire line are sharp, well designed and easy to use.  

They are cost effective, useful and they sound good. They are available in various bundles so be sure to check out www.kuassa.com.


OD3603 Overdrive

Rating 3.5/5

Rating: 3.5 out of 5.

Overdrives and tube screamers are used plenty by guitarists and bass players in almost every genre that employs the instruments. Having a good OD / TS can help push a clean amp to be a little angry or focus and push the signal going into a high gain monster. I also like to use one in my country guitar signal chain to add more attitude to the twang.  

Kuassa’s OD3603 has a selection that covers all of the above jobs and a lot more. Blues, Boutique, Mad, Modern and Pro are the five options and all of them have very different ways of getting the job done effectively.  

I really found that this pedal, even boasting five pedals inside, just didn’t like some amp sims that I used it with for whatever reason. It took time to find the right amp sim match for the five pedals but they were worth the search.  

DS3603 Distortion

Rating: 3/5

Rating: 3 out of 5.

Distortion pedals aren’t as widely used as they once were. So many amps these days have distortion and gain that vastly outdoes and overpowers any pedal but that wasn’t always the case. Distortion pedals were once one of the main choices to get mid to high gains. I would say that traditionally, distortion pedals should be used on a clean or slightly driven clean tone for best results.  

I managed to create some nice crunch tones and a few gorgeous lead tones that I really spent time enjoying. I feel the crunch and lead tones are the highlights of this plugin and I’ve used it for both since its release. Of the five types of distortion, I really don’t have a clue what they are based on.  

On the downside, this plugin has little to report in the high gain department. I’m not sure I would have reached for it for high gain at all but given the heavy and metal inclusions, I had to give it a shot. After doing so, I’ll just say that I wouldn’t reach for it for anything above mid-gain.  

FZ3603 Fuzz

Rating: 4/5

Rating: 4 out of 5.

Five types of fuzz and five ways to make your tone a beautiful pile of filth. I say that in the best way of course because for me, when it comes to fuzz pedals, I think stoner / doom type stuff. These tones need to be gross by definition, FAT, saturated and generally full of life. The FZ can help you with all of the above.  

Five types of fuzz highlight the features and all of them are useful. Vintage, Zepp, Trans, Sustainer and Big all provide a different look at the wonderful world of fuzz. It’s a vast world but these five can give you more than enough to get fuzzy without a lot of effort. That said, every amp I tried responded very different to the FZ so dialing things in can take some time. 

Monstrous doomy tones are everywhere inside the FZ3603 and it’s a damn fine value as a result of being so versatile, if even inside a small category of gear. Crank all the knob up, dial it in meticulously or just go with the flow of whatever song you are working on, Kuassa’s got you covered. 


CH3604 Chorus:

Rating: 4.5/5

Rating: 4.5 out of 5.

I am a huge fan of chorus pedals and chorus effects so this one has seen plenty of use in my DAW. Kuassa include three chorus types called Dimension, Tribunal and Ensemble inside this plugin so it covers a ton of ground. I like it for tone chasing because there’s three types of the effect right there at my fingertips.  

Once you have become used to the plugin, it’s pretty easy to at least get near the chorus style tones you might be after. The controls all have a lot of influence on the tone so when you need those micro-adjustments and whether clean or on a crunchier tone, the job gets done. 

FL3606 Flanger

Rating: 4/5

Rating: 4 out of 5.

Personally, I have never really employed flangers in my tones but, I definitely see the allure and uses. Many players however, love their modulation and flangers can be heard on some of the best albums ever made.  

Kuassa deliver Royal, Jet and Electro style flangers inside the Efektor FL. The uses really are endless if you know how to use a flanger. It’s an effect that in my opinion is much better when used sparingly and subtly but that’s a matter of taste. Flanger is an effect that can very easily take over and ruin a mix if used incorrectly. Thankfully, the three types you get in this plugin cover a lot of ground, which should make finding the right one for your mix easy.  

All three types of flange included are truly well executed and the controls really have a lot of life to them. When any modulation is poorly done in plugin form, it’s easy to hear it but you won’t hear it anywhere in this entire line.  

PH3605 Phaser

Rating: 4/5

Rating: 4 out of 5.

Man do I love a good phaser plugin and it’s been a prominent effect in many signature tones. Phasers and Flangers can be used in similar ways but I feel the phaser has maybe a little more prominent.  

I used the three types of phasers (Phase one, dual phase, multi-phase) in the PH3605 to create EVH / Van Halen type tones, old school country, smashing pumpkins type parts and more. All three offerings were made with care and have come through for me on more than one occasion so I would very much recommend this plugin.  

Like the flanger, a phaser effect can also be tough to tame out of a mix if it’s not done right so be careful when calling on modulation and save yourself some mixing headaches later on. 

TR3604 Tremolo

Rating: 3.5/5

Rating: 3.5 out of 5.

Tremolo is an effect that for me, has to be used sparingly but it can be used with a lush reverb faded into the whole background of a song as well. To really create different atmospheres, the TR3604 provides sine, square and triangle / sawtooth options. I had a lot of fun experimenting with delays as well, you can really create some unique sounds like this, that’s for sure.  

Everything is done nice here but I would consider this more of a utility kit type plugin rather than something everyone needs. While it’s not one of the “must-have” plugins in the Efektor line, it’s still made with quality.  


Efektor Silencer: (freeware)

Rating: 4/5

Rating: 4 out of 5.

This is a FREE noise gate and if you have watched any of our videos, you will have likely seen the Kuassa Silencer in one of many of our signal chains. No need to go too far in depth but EVERYONE requires a gate for tracking and mixing etc and this one is free so it’s a no-brainer. Go grab it and have it help to keep your guitar tracks in line.

CP3603 Compressor:

Rating: 3.5/5

Rating: 3.5 out of 5.

The Efektor compressor plugin provides three types of compression; opto, VCA and FET. All three compressors inside the plugin are more than useful. I put it through a number of applications and it crushed them all (pun intended). Add some snap and stank to your telecaster, thump to your bass and really 1000 other uses.  

This pedal plugin is a nice tool to have because compression is always a need in any mix so having options never hurts.


I like all of these pedals but some I found more useful and higher quality than others. The one downside is that it’s hard to comment on realism because Kuassa prefer to provide their own take and own design on a lot of gear rather than providing exact replicas. I will say however that the pedals are all effective at what they are meant to do and they do so without a lot of hassle.
