Mine too, that 2T with the Thunderbolts winding up in the background has to be one of the creepiest sounds I've heard. I wish I wasn't surrounded by single tones
One of my faves, too. I like how the 2T has an almost synthesized sound, sounding like sawtooth waves.
More of my faves:
The Pierce, NE xT22+ M-10
The bolts&m10.mp3 file that was posted a loooong time ago.
The ?Mooing? Thunderbolt clip (go outside, 'ya big chicken-s#%t!/I.. I AM outside!!)
