I like to record dry signals and add reverb in the mix.
I have some usual suspects (Had UA stuff, have Waves, etc) but I must say I have not been very happy with them.
I loved the Reverb of the ULTRA when I had it for a smooth and natural reverb that works for my tastes (I sold it and it's still not post-recording)
I recently jumped on the Eventide UltraReverb plugin offer and it's what I like thoroughly for guitar as well as vocals.
I'd like to hear if anyone else has or has demo'd this plugin.
