Maybe it's just because I'm so familiar with the easy to use Waves' Renaissance De-Esser, but I found this de-esser to never get it to sound the way I wanted. After talking to several other fellow UA junkies, they too agreed that this plug-in is not up to par with other de-essers. One of them said "it either does too much, or not enough," which accurately describes my feelings with this plugin.. However, it came free with one of my hardware purchases, so I'm not too upset. My love for the 1176 Classics Collection and SSL Channel Strip make up for the quality of this plugin!
I do not love how this De-Esser works there are much better De-essers around which work better in my opinion.
