This thing will give you level without increasing your peaks, if you hammer it. Thank Klanghelm. This is an awesome compressor.

I started with Klanghelm's free MJUCjnr as I wanted a more characterful warm tube compression effect not unlike a Fairchild 670, as I loved the sound of all the various 670 dems and reviews I'd watched, but thought them all pricey - too risky a purchase for the money being asked ($100ish)

The free MJUCjnr seemed to give this warm Fairchild-ish quality as it's a Vari-mu compressor, which I'd learned a surprising amount about after studying loads of 670 plug youtube dems.

Vari-mu compression was virtually unknown to me previously, but sounded so lush in the 670 dems I'd heard.

From a casual download and try-out, I quickly found I loved MUJCjnr's warm thick sound and was using it on almost everything as it lifts everything up in such a seamless feeling way that never seemed to spoil the music.

It almost never sounded wrong, and was awesomely easy to use. It always just seemed to work.

This is apparently due to the different ways a vari-mu automatically responds & adapts whatever input level you drive it with.

So I sprang for the full paid up MUJC.

Fabulous buy.

The paid version includes the all important attack/release preset knob, as on a 670,. This is really fun to use once an overall input drive is set. It's an important feature that the free MUJCjnr lacked. The latest version also has AutoGain which is nice to have in a budget priced plug.

Also got 2 additional vintage style comps in the pack, but find the Tube version vari-mu 670 effect is still my favourite.

Nonetheless having two alternative compressors readily available, a click away within the same plug, is quite handy for AB comparisons.

I can't pretend to know how accurately the MUJC matches the original Fairchild 50s limiter, but I do know I like what I'm hearing. It's a sound I've been after for a while. Warm, rich, never harsh.

Even driven hard it never seems to upset the music, and the tube character is so wonderfully warm and thick without ever getting gritty.

And even when driven very lightly it still adds subtle tube warmth.

It works on individual tracks and works fine on any mixbus, and increasingly also on my master bus, normally the sacred territory of my Sonible Smart Comp.

If you're looking for a Fairchild 670 sim on the cheap then maybe this is it. A genuine pro quality plug for little money. The Beatles always used it, which was what drew me in the first place.

Trying out the freebie MUJCjnr is worth the bother as you get to hear the essential 670 sound, certainly enough to make a decision over whether this is the right thing for you.

I don't normally write reviews anymore, but MUJC has been such a success for me, I thought to share my feelings with you.

A lot of free spring reverb plugins basically just sound like slapback delays, but this one is actually pretty authentic (i.e. the reverb tail is pretty diffuse). It's not super versatile, but that's just the nature of spring reverbs, and the included tone-shaping options do help a little bit.

First thing I found after getting this was the authentically tube-ish, harmonic MIRACLE it did when I applied it to a drum track...I simply stick 2 or 3 $12.00 Pyle sm57s and an Octava-brand condenser haphazardly about the drumkit and press "record" -- good enough for The Kingsmen when they recorded "Louie Louie"; PLENTY good enough for me. This prompted me to buy the paid version, which has 2 additional modeled compressors, and, since I was drooling over the site anyway, I also got the "mixer desk" sim, which has interesting models of various mixers' elements, sounds good...though I'm vague on what that one is used for, exactly, as the models incorporate compressor and 2-band eq, which are both very mild in their effect. May have been better without those being in the way of my "real" comps and eq channels, and to have just left them as colorization VSTs. But meh, they're still great. The paid version of this compressor is only about 2% better than this free one. But yeah, this free compressor lends major wonder to any track you use it on.

This one is clear 5 star winner. Its very often listed between the best free compressors and really deserve this position. From technical audio measurement it is better then very good AO compressors and comparable to best paid ones in the industry.

There is more advanced paid version of this plugin - Its worth every penny.

Extremely handy plugin. Subtle application of IVGI works magic for the character of any sound. I have another free saturation plugin that I use all the time. But for the parts of the mix that really matter...I use IVGI.

I really wanted a different compressor from the DAW native I was using. I put in research, I found some compressor plugins on sale, and then I found MJUC. For a little bit of money, you're being given three different compressors with their own character, a really cool UI, and a rich sound. The dedication that went into this VST is incredible (you can read about it on the website for Klanghelm) So really what you're getting is a world class compressor plugin that doesn't cost $300 or more. That is so cool. Tipping my hat to you Klanghelm.

A great compressor if you're just learning how compression works, or if you need to quickly throw something on your bass, guitar, etc. Subtle settings also help glue the mix together.
