Balu. It will work in your Piggy too, with the adjustable cork system they have. Great sounding on my big and small horns.

FAXX makes a large 6/4 sized metal mute that is quite innovative. I was at the company that distributes them and they had several sitting on the shelf. I just don't know where you can order them as they have never really been advertised anywhere so no one knows they exist. You can't buy them directly from the distributor and have to go through a dealer.

Just my $.02.

Here's the only link I was able to find for someone actually selling a Faxx tuba mute and there's not even a picture:

Have you taken a look at the Humes & Berg Symphonic mute? I use one for my 186, but it seems like it would work even better on a 6/4.

Doh! Yes, you did say that, and I forgot. There is now a large palm print on my forehead.
