Flughorn 28.12.2024

I bought it for recording bass at home, so i have access to the computer all the time when using this pedal. I installed the neuro app on windows and there was no problem. For community plugins you need a neuro account though.

It is like having my favourite and best sounding compressor plugins in a pedal with on the fly adjustment capbility and possibility to take these with me wherever i go. That is exactly what i wanted. On top of that there are compressor models that i didn't have experience with. It is like a lesson of compressor types and their characterisitcs.
Look and build quality is flawless despite the pedal being mad in china.
All necessary cables and gimmicks are included i.e. power source, usb cable, rubber feet...
The layout of the control is a compromise between having many options but not to overload the pedal. The result is not optimal för either minimalistic purists nor the all control under the fingertips type of people. Compare it with the newer cali or empress kompresors that have 6 nobs or more but neither have stereo capability, nor dual band compression nor choice of different compression engines.

The LED that indicates the amount of compression is mildly helpfull but encourages me to actually use my ears. In contrast with my mxr bass compressor i alwas look att the LED ribbon and think 10 db gain reduction.. isn't that a bit much, even though it sounds fine.
This will not happen with the Atlas.

Learning the pedal takes 1 min, learning the app--- a little longer. If you are willing to put in this small effort and you have the ability to adjust the things you need to adjust you will be happy. There are manuals and videos that will help you get the most out of the pedal.

Don't forget to put the pedal inte bass mode (hold alternate when starting up). It will remember this choice so you only have to do it once.

I would recommend for anyone that appreciates flexibility and is not thrown off by the layout.

The most versatile compressor pedal

dragoje 15.09.2025

I understand people who detest menu-diving and prefer simplicity, and this pedal is probably NOT for everyone. But I have to say that even the on-board factory options are great out of the box, especially once you select a prefered mode (in my case the bass mode).

The biggest suprise for me is the fact that they didn't sacrifice sound quality by adding a ridiculous depth to this compressor. The digital versatility is unmatched, yet the sound somehow feels like a quality rack compressor. The fact you can store so many different compressor presets and recall them from an external source, while having the option of an external sidechain control is something which really sets this thing aside.

A very powerful tool for a live gig or studio use, but also a great learning tool if you want to understand different types of compression and hear how they work.

Great solution if you need a lot of different compressors

WesBes 02.12.2025

I haven´t had time to deep-dive into this, and have just been using the presets. Actually - that is why I bought it in the first place, so I won´t need to tweak for ages! Seems to me It can do whatever you need it to do. Purists will surely prefer the real deal, but for me - which needs a lot of different types of compressor - this is a great quality solution. It is well built, sturdy knobs, lots of functionality and so on.

Chaud, profond, discret.

Saturn-Y 18.07.2022

Cette opinion ne concerne pas l'aspect "musée des compresseurs", qui dépasse mes compétences, mais une utilisation simple sur un synthétiseur FM. Je l'utilise pour améliorer le son un peu étriqué du DIGITONE. Le résultat est à la fois excellent et discret.
Je branche l'ATLAS en stéréo sur le DIGITONE, je choisis celle des trois positions principales qui convient au morceau que je programme, puis je règle le seuil de compression très facilement grâce à la lumière qui change progressivement du rouge au vert quand on tourne le bouton pour trouver le "sweet point".
Le son devient riche, les basses et kicks vous prennent au plexus, et le grain de la source audio est cependant préservé.
Une petite critique négative : le sélecteur métallique au milieu des potards est un peu rikiki. Il semble assez fragile et, à chaque fois que le manipule, j'ai peur (probablement à tort) de le casser. Cependant la qualité est au rendez-vous, je ne regrette pas du tout cet achat.
