I was at a corporate function at the legendary Ryman Auditorium here in Nashville last night, maybe 150 people listening to a guitar pull with 4 songwriters of some repute. .really got a chance to appreciate the sound of the room. How would one go about capturing an impulse to use with SIR or equivilant impulse reverb? Now I need to figure out how to get in there on the off hours and do it!
