The final polish: patch the voice into a stereo reverb. The dry rack suddenly has a room, a cathedral, or an infinite plate around it.
The dry voice is done. Now we put it in a room.
A reverb module simulates the reflections of a space - small room, big hall, endless cathedral. Patch the voice through it and it gets a sense of depth.
Four cables: VCA -> Reverb IN L, VCA -> Reverb IN R, then Reverb OUT L -> Output L and Reverb OUT R -> Output R. The Output jacks are empty right now - the reverb is the last module in the chain.
Tip
The reverb's Mix and Decay knobs are unlocked. Dial them in to taste.
