Sounds really great
The sound of the Sidewidener II is absolutely fantastic. I had bought other widener plugins before but they caused phase issues the sound was more like a chorus effect. Can be wanted sometimes but I wanted to use it on vocals. I put it on and was just amazed how clean the sound still was while being really wide.

Great mono to stereo plugin
I was skeptical at first but after using the trial I had to buy it. One of the best plugin I've used in a while

Best ever!
I have used Sidewidener for many many years. Its outstanding. I have tried a lot of other plugins for "Stereowidening and bla bla bla" but Stereowidener has always been the king. Now I have the Stereowidener 2 and its even better! Perfect in every way.
