The Neumann TLM102 records amazing acoustic guitars, both classical and steel strings, in an untreated lobby located at the Sound Pure facility. While the room does have some nice natural reverb, it has no acoustic treatment which demonstrates the excellent performance of these microphones even outside of a recording studio.
