Look to get the double vocals you been looking for record your main vocal then clean it up take out any background sounds hissing and so on then add your effects to it this is mostly a light reverb ,compression not to much and eq is a must after this to get the double voice copy then paste your main to the next track ,now zoom in and move the copy to the right a little not to much but just until you here the double voice to much sounds like shit there you have it
