If the goal of a live recording is to record the instruments as faithfully as possible to the source audio, wouldn't a measurement mic with a flat response be preferred over a mic with a response that's not flat?

For example, if I wanted to record a guitar playing through a 1x12 cab at a reasonable volume, wouldn't a flat response mic be preferred if the goal were to record the sound coming out of the cab as accurately as possible?
