TC-HELICON VOICELIVE RACK. It's the Piece of equipment what I like very much. After so many years, I try out different models effect processors from different companies, finally I have thing what I always wants to have. Is not necessary to write what this processor does, after all you going to have a very good manual. That?s why I will focus on two things; 01. The preamp is amazing, believe or not that is the most important thing on the processor. This is where the big sound comes from, if you have good preamp then you have good sound. And VOICELIVE have very good mic.preamp, Very soft sound even in the high gain. 2. Another thing I like very much is adaptive EQ Before I got this type of EQ it takes lots of time till I have good sound on the lead vocal. But I don't have this problem anymore, now I'm Happy. Those two things combine with all other effects, make life easier. I don?t have any negative words to say about TC-HELICON VOICELIVE RACK.
