Why do amps make guitar notes go on forever?
QuestionWhen you play an electric guitar without an amplifier, the sound dies out immediately. But if you plug it into the amp and it’s near the amp, the string maintains its vibration for a long time and the sound gets louder. Why does this happen?

Answer: When you let a chord ring though a high-gain amplifier, the amp is producing the same resonant frequency as the string, so the soundwave is vibrating the string at the same time, creating a constant feedback loop.
