The Siren Board

This is one of the sirens that was destroyed in the 2013 tornado. This is a newer Mod with the UV controller, probably one of the last few of the previous generation to roll off the line.

The nearby 2T22 did not go off, but you can hear the 2001, a 508, almost all of their Thunderbolts, and a handful more Moore Mods.

Dual tone Modulators have always sounded extremely eerie to me, I love them. This is great, love the ambiance too!

I can't imagine the feeling of hearing this while a tornado was approaching!
