Gotta love how the engineer Lays into the Leslie S5T at 0:42 https://www.youtube.com/watch?v=d_iGoQ2k7Cg
I think I know what horn I will be buying next 
Tight fit through that tunnel. Shame he didn’t let rip inside it. … then again, probably values his hearing too much 
That horn is definitely on my list of must haves
Wow, that has such a resounding ‘Get the f**k out of my way!’ sound to it. If only I had the means and the mount space for a set…
