@Newell-Post It's an old post, but am new to the BOARDS. If you have the YAMAHA Neo Eb cornet, why would you have needed another?
Some other thoughts: I play the 8320S cornet and find it the easiest to play in tune and in higher pitches with British recordings. I also have a Getzen Eterna Eb cornet, the one with a larger than life bell, and it sounds as big and round as anything I ever played. I just have trouble getting my pitch high enough for European standards even with short shank mp's, so I use the 8320S mainly. I also have an Eterna Eb trumpet that is solid, and a couple of YAMAHA Eb/D trumpets, but the YAMAHA 8320S get the job done in brass band.
