I use two mouthpieces, a PT-83 and a Helleberg on my 1960 conn 5j from school. I use the PT in the comunity orchestra and the wind symphony at school while I use the Helleberg for small groups and solos. I think the PT has a bigger easy-to-blend sound and less trombone-like in tone while the helleberg is more focused and makes a more characteristic sound for the horn (in my opinion). I could play just on the PT but I like the way the helleberg sounds on some things (ex. Solo Pomposo by Hays).
anyone have any bad/good habbits come out of doing this?
