I saw a video on youtube of a guy playing a hoseaphone and I wanted to try it out for myself. This was the mouthpiece I bought, it's good value and fitted directly onto the clear plastic tubing I had. It's not an easy thing to play (unless you're a trumpeter!), but enabled me to get some interesting brass section sounds that I can manipulate in my DAW. I'd recommend it, but you won't sound like a professional trumpeter without a LOT of practice! Good value, solid mouthpiece.
