I recently overhauled an old Yamaha 62 tenor and after setting it up I started testing the intonation and noticed everything was at least 20 cents sharp. So I messed with my corks because the pads I used are very thick. Nothing changed. Someone told me to try a different mouthpiece that mine was too short. I play on a Vintage Dau Han 4 hard rubber mouthpiece. So I slapped my good old selmer c star on it and bam played perfectly in tune. Now I bought my little brother this same mouthpiece because he loved it so much after playing on mine and he also plays a Yamaha tenor so I asked him if it made his horn sharp and he was like yeah I just adjust because I like the control of this mouthpiece better so I just deal with it. So my question for everyone is how can I make this mouthpiece work with my Yamaha? Or how can I figure out the specs on my mouthpiece to find someone to make me a longer one that will work with my horn? I really don’t want to give up this mouthpiece because I love it.
