Ok, I have been negleting the C mel as of late...lots of Alto needs during the holiday season. Anyhow, i pulled her out again a couple of days ago and played through some scales and etudes to warm up. after a while, I noticed my low C, B and Bb are burbling...a lot. I have always had to open up the oral cavity on the low notes and think about them on this vintage horn but i just could not make the burble go away for the past couple of days. I leak lighted the horn yesterday and did find a slight leak on the G pad...adjusted it and thought, ahhh...that sould fix things...not :evil: Burble is still there. object in the bell does not make it go away either.
