Blue Hummingbird drum room(s) by Pro Audio Review Magazine published on 2015-07-14T23:03:44Z Here are two mono recordings (different drummers, different sessions, same room) of a Blue Hummingbird on drum room (approx 11 x 17) about six feet behind the kit. Both used high grade mic amps (Manley, Sytek), but were quite firmly compressed with a dBx 160X before conversion. Other than that there is no processing or EQ … raw audio. Genre Blue Hummingbirds
