Thanks MuddySludge , yeah for me it’s pretty much what this guy said :
Quote from Michelangelo di Lodovico Buonarroti SimoniThe sculpture is already complete within the marble block, before I start my work. It is already there, I just have to chisel away the superfluous material.
Of course I don’t throw my profiler or guitars down a hill to see if it still works before playing.
