wanting to buy 1 or 2 bosch 12 volt fan fare horns

is it a MUSICAL ONE ...plays a tune?
i have a dual or three but dont think plays a tune ..

hi bushed no not musical as such but a true set are pitched at different tones so would kinda sound like a tune when together chrome dome with a small chrome grill at the front

ie merc and my KG ones !!
some horns (vw Boschetc ) are adjustable to give it different pitch to the twin
could not download pic said was corrupt
so maybe email me bberni@westnet.com.au
