"Tobin soon got his hands on a Nagra IV-S portable reel-to-reel tape deck — the latter-day descendant of the ever-reliable and rugged unit that has been used for decades on remote film shoots to capture ambient sound and dialog while on location. Supplementing that with a pair of high-definition microphones by Earthworks Audio, Tobin and Cousins were ready to dive in, criss-crossing the country on a quest to amass as many animal and machine-made sounds as they could get in roughly a nine-month period."more
These microphones are overall great mics. I use them to mic the drums, room mics, mic violins or other string instruments, horns, large groups of vocalists. They are durable and can be used to pick up the entire drum set without other microphones.
