Simply recording a siren and putting the mic inside a Thunderbolt horn are two completely different things. A 100 watt Marshall is miniscule compared to a Thunderbolt siren. Just doing a b.s. horsepower conversion with 10 hp (chopper/blower motor hp of Thunderbolt) using a conversion hp/watts calculator online 10hp is about 7500 watts. I know that's not a direct conversion but still. I guess if you could cram 70 Marshall stacks into a Thunderbolt horn that would be similar comparison. I don't see how a microphone wouldn't completely fail if exposed to the sound level in a Thunderbolt horn running with a blower.
I will agree a 100watt Marshall stack is a drop in the bucket compared to large siren.
Though it would be interesting to set up 70 marshall stacks together and play a Thunderbolt recording through them at top volume and see how far it carries
The point of my post is, If any mic can take the SPL of a T-bolt while still providing good sound quality, it would be a SM/Beta 57.
I'm not sure of there is a good way to do a close up recording, the best way would be to experiment with different distances from the horn, but this is a one shot deal, and I sadly don't think Josh is going to make it out to holler's or kx250rider's anytime soon to experiment.
I would like to experience a 1000T/1003 in person sometime, but preferably from a distance (though we all have that fantasy of "Riding the T-bolt" *Koff* Ian *Koff*)
