What & When & Where… back or forth... is in the transducer. “Good” or “bad” is in the consumer.

A microphone or speaker (or whatevs) is electroacoustic. There are more types than one can afford. Selection and placement of both is both science and art.

With minor exception, a speaker driven from an electromechanical input is not recreating acoustic energy.

Pick-ups are electromechanical. Piezoelectrics will respond to acoustic energy only after it encounters the mounting surface and has been converted to mechanical energy. Magnetics will respond to any field present including noisy mains and guitar strings. There are engineering pros & cons to both types.

“Likes” are just that. An acoustic guitar on a shellac 78rpm record is still an acoustic guitar regardless of the sound quality.
