Jeez that thing sounds so freaking cool! I wish i could’ve been outside to hear it

[@GamingWithJonny3612]

Very nice!

Sweet!

[@southwesternpasirens]

Wow that sounds really good for a STH-10

[@Alco16-251F]

That is one hell of a siren right there. I love when these have GE motors because it really gives them that punch that makes them sound really healthy. All the STH-10s I’ve recorded either had factory newer motors if they were 70s and later or the valley motor if they were 60s and earlier. Too bad I couldn’t have been there for this.
