Me? I like mine big and pointlessly loud, be it a Leslie 5 chime welded to the underside of a Trabant, or one of these two, no. 1 The Concert and no. 2 The Kettle.
Just about every American horn will, as my father puts it, make my head cock like a dog. I really have a thing for British toggle-horns, like on Class 33 Cromptons especially. And it's even funnier when Mark Williams has a little fun with with Class 31 D5528's toggle switch.
