There have been one or two posts addressing the difficulty of hitting C# on the LH pinkie cluster. I've taken my 1968 Buescher 400 tenor to a very good tech, and he's lightened the action as much as he can. But it hasn't made enough of a difference because it didn't address the leverage problem. The key is much closer than the B and Bb so that your pinkie has to curl and push straight down. One member said he felt he needed to get his last pinky joint amputated in order to hit that C#! Any new ideas out there?
