Problem Solved.
After going through the arsenal of trumpet mouthpieces I have collected through several decades, I finally stumbled upon one which has been shelved for more years than I can remember; my old Purviance 5*K4.
Today I played the first half of the show on my usual Bobby Shew Jazz mouthpiece and the second half on my old 5*K4 and my old standby saved the day again. Every note in the middle range which was covered by the lead trumpet playing in his high range finally cut enough to make balancing the two parts perfectly.
Tonight I will now have to “dial the new mouthpiece in” with my horn to complete the switch. I was amazed at how the two horns are now equal in volume balance without having to increase my decibels.
In the future, I may have to fill in on the lead part again like last season and at that time I will be looking to the Purviance 4*K4 for even more edge to my sound, but for now, The 5*K4 is the answer I was looking for.
You might keep this in mind if you are faced with a similar situation.
