Federal Signal Thunderbolt 1000 | Growl Tests | Murfreesboro, TN

Originally Recorded 1/7/2023 & 9/3/2022

Here’s a short compilation of Music City Siren’s Thunderbolt 1000. The head is an ex-Chattanooga unit made in 1954, coupled with a 6m blower from Cincinnati. The original blower was electric, but converted to gas in this case due to power constraints. The siren itself sat atop a public housing complex and could be seen from the Interstate. I actually remember passing by when I was in Chattanooga about ten years ago. I never thought I’d actually get to hear it go off someday.
This thing is crazy loud, especially at this distance. I know I say that with a lot of siren videos, but this tops them off. All three of my external microphones were maxed out. My main camera experienced extreme vibrations that made the video look like jello. So a lot of the shots I used came from after the test. Only my iPhone came out with usable video, and surprisingly good audio. It’s the only mic that didn’t clip somehow. Either way, I had a lot of fun hearing this beast and I hope to get a more proper recording once again.
Again, a big shoutout goes to Music City Sirens for setting this off!
Enjoy, and as always comment, like, and subscribe for more. Thanks!

Is that the pulsating effect caused by a 6M blower? It's interesting to hear.
