So I keep reading that a lot of you quad track your mixes and pan 2 tracks hard L/R and two 80% L/R... but I need clarification on something, I apologize if this is a very stupid question. Assuming two guitarists, does each guitarist perform his part 4 times? and then each guitarists' parts are panned as mentioned? giving a total of 8 performances? or does each guitarist perform his part two times, then those tracks can be copied onto other mono tracks and panned as mentioned about, giving a total of 4 performances? or is this double tracking?
