Top producer and mixing engineer Greg Wells (Adele, Katy Perry, Weezer) has been using H-Reverb on his tracks since it was in BETA. In this excellent video from Waves Audio, Greg explains his process for using H-reverb on vocals, including his own presets, and also what makes H-Reverb superior to other reverb plug-ins. (Spoiler alert: We're talking about how H-Reverb deals with the end of the reverb tail.
Anyway, watch the video if you want to learn more. H-Reverb is certainly worth checking out.
(Please note: The version of H-Reverb used here is a prototype of the plugin with a slightly different graphical interface, but otherwise identical to the final product.)
Oh, and H-Reverb is currently on sale for just $199 (normally $349).
