Siren Simulation | Federal Signal Thunderbolt | All Chopper Levels & Port Ratios (1,000 Sub Special)

Thank you all for 1,000 subscribers! I've been working on this for a few weeks now, and at long last, here it is! This is an improved version of the synths I made about 5 years ago of the Thunderbolts on all chopper levels, only this time, they're all combined into one video, plus I added high/low for the 4/5 and 5/6, which I didn't do last time. This is the first synth I have uploaded for about 2 years now, but I've been experimenting a ton recently with just about everything there is to experiment with. I think this is my best synth to date, and I hope you all like it. Also, if anyone is wondering, the Thunderbolt in the photo is the one at the Massie Township Fire Department in Harveysburg, Ohio. I took that photo a few weeks ago after recording the 5M 4/5 in Clermont County. Enjoy!
