If anyone knows of any free verbs as sweet sounding as Glaceverb, please let me know! I really like the sound of this reverb. I have never owned a high end verb like a Lexicon, so I'm not really an expert at what a good reverb should sound like, but compared to other soft reverbs, this one really stands out. It is not a transparent reverb by any means, it has a warm "colored" sound to it that sounds great. This is a plug-in with character.
I've gotten some great results that remind me of the reverb sound in some new wave/pop recordings from the 80's. I've used it on piano and tweaked an awesome jazz lounge reverb sound. It takes a bit of tweaking to get it to sound right, but with a little work the results are very good.
I also use Ambience which might sound a little more transparent and natural, and Ariesverb, which is unbeatable for long sustained reverbs and FX, but I prefer Glaceverb's sound for the aux bus in a mix, the sound just works. Not too thin, not too dense, just right. Try it out for your self, It's free!!
The best free reverb IMHO. It can compete with other commercial options. To get all the juice you have to play with the controls and not use the presets. The presets are just a starting point for those who do not want to invest a lot of time. This one is an example of what it is possible to do with Glaceverb (with mi own configuration):
