Some hissing/buzzing is present is in my sound and it's really bugging me. It could be an equipment issue, or it could be me double-buzzing or something I don't know of! It's not really terminal but it's noticeable! It's really audible in the lower registers like 2nd line B-flat and below. I'll probably record myself and ask members of the Trombone Forum for advice during the weekend. Now I need to get the momentum going for my exam pieces!
