Trombone, bass trombone, and baritone work well with a large diaphragm condenser mic placed about 2′ from the bell.
Tuba, sousaphone, and euphonium work well a large diaphragm dynamic or condenser.
These lower frequency instruments need to be mic’d farther away in order for the sound wave to develop. Mic too close and you will not get a good balance the lower frequencies.
French horn or horn (as it is called today) is a very different animal. So much of the sound is controlled by placement of the hand in the bell. The sound is very mellow not much attack. Use a large diaphragm condenser placed about 18” in front of the bell.
