Quote from: Doug Elliott on Dec 12, 2017, 08:50AMYou can get an almost identical sound by blasting with a plunger tight against the bell. I use that technique a lot to blend with trumpets in Harmon.
I think the Jo-Ral bubble mute is a much better choice than a traditional Harmon,but I don't have one. I think there are one or two other brands but I haven't tried them. I do know that an unmodified Harmon will not fit a large bore horn, you have to add cork to it.
Either way, they like to fall out.

5 hours, 30 minutes in, that's me in the middle-right there when my mute dumps out of my bell...
And no, it wasn't my mute either...
I don't know of a Harmon style that works very well with a large bore, so I have never bought one.
