I never knew that! Will see if I can get a decent tune off them!!patriot66 said:Hi Stu.
In the past my horns played up a bit and upon investigation on top of the horn there is a small cross-headed grub screw covered in a sealant goop. If you carefully turn this one way or t'other whilst someone constantly presses the horn push you can find a 'sweet spot' and sometimes get a reasonable sound out of it...for a while. They always seem to die eventually. In the end I replaced them with a new pair :roll:
