Like the original review post by jam92189 states, I too have recently purchased the Track Essentials suite of plugins. I had TB ReelBus and TB Barricade already, and since the quality of the ToneBoosters plugins that I already owned is so good, I bought the Track Essentials suite with confidence. Right off the bat I'll state that the pricing structure of Waves plugins, and similar, were out of reach for me at this time. I have not been disappointed with TB DeEsser as an affordable alternative.
I was "getting by" with the wonderful (FREE) SpitFish as my VST DeEssing plugin of choice. I will always have respect for Digital PhishPhones plugins, but I did need something a little cleaner sounding and a little more professional-grade. TB DeEsser easily hit the mark and has yielded very good results. The quality is very, very good and the fact that the plugin bundle is so affordable is a serious bonus. I've become an ardent admirer and supporter of ToneBooster plugins.
It's easy to dial in the correct "de essing" settings while retaining a clean, natural-sounding vocal track. The (2 band) setting really helps to take care of the sibilance and also the lower frequency "FF's" and "TEEs".
1.) Very high quality
2.) Very reasonable to Low CPU consumption
3.) Attractive, well laid-out GUI
5.) Regularly updated and well-maintained
6.) Easy to register and no "commercial" protection mechanisms (iLok, anyone?)
7.) Honest, and high integrity developer
As a summary, suffice it to say that ToneBoosters products are exceptional value for both aspiring home recording enthusiasts and also semi-professional home recording engineers.
