That's the sort of anomaly that makes recording with acoustic instruments real and gives it heart. Listen to quality chamber music recordings. You can often hear bows & breaths, along with the clicking of keys from the clarinets, oboes, and bassoons. Music perfected under the scope of sound wave machines would ultimately be sterile and dead.
I listen to a lot of that music iuventus. But when a sound stands out too much, and sounds unnatural compared to the other guitar clicks in the same track, which I sincerely doubt this is, it needs treatment. I know. I spent months discussing the mastering versions with Emika of her last album I shot the cover for.
