If you are using a reverb box, and most everyone does, and you pick a medium hall, for example, the WETTER you turn the wet knob, the more reverb you get. Too much of that will make a vocal sound like it is being sung from the belly of a T-rex.
So, you have to experiment with your reverb unit to see how wet you want the reverb bounce; different reverb rooms or "settings" produce different options for wet/dry settings.
Suggestions: drums need very little "wet" or very little reverb; vocals need reverb to enrich the sound, like the big studios do. A sax solo with a "type" of reverb room will sound groovey, as well as flute, and to a certain extent, strings.
You need to experiment and experiment and you will find the wet/dry mix you like. It is your ears that do the evaluation.
A GOOD reverb box will make you happy.
