2 problem notes on Bach B flat trumpet - help needed, please I'm just getting back to serious playing after a long while and am noticing that my d (_OO) and e (OOO) within the staff are much flatter than I'd like. It's a great horn otherwise: 61,000 series, professional grade, Bach B flat. Great response. Great, dark tone. I purchased from Luther Didrickson while I was at NU. Bob Reeves valves alignment 20 yrs ago, with pads replaced a couple yrs ago. I generally play a 1C or 3C mouthpiece. My valves have been sticking so I'm planning a valve job. I need the valve job regardless, but could valve wear have caused it? Is there a fix for this? ANY SUGGESTIONS WELCOME! Thx.
