The mic's either a magic wand
Or it gets tragic like the havoc of a nuclear bomb
Guru is saying that a microfone is only as useful/good as the person using it. If a person who can’t rap uses the mic, it will only make them sound worse, or vice-verca.
“Tragic like the havoc of a nuclear bomb” was sampled in Royce da 5'9"’s song “Boom”, and is probably one of Guru’s greatest ever lines. Sit back in amazement.
