Well written. I do not have a go to chain. I will use what ever is needed for that specific singer and that specific room get the best sound possible.Going back to fundamentals, I would say that my "chain" first consisted of understanding how the space sounds when you sing. Is it dead and if it's alive, are there any sound artifacts that might come through in the recording. Does added reverb work to treat a dead vocal? Or should I look for a better space to record the vocal track?
Second, I think about the voice itself and what kind of mic is the best match.
