I currently play a Yamaha 8310Z and find it's the best-playing horn for me of the many I've had. However, like new car fever, I keep finding myself wanting a Schilke. Several months back, I was trying to decide between a B7 and the 8310Z horns. I bought the 8310Z primarily based on price and am not dissapointed. Understanding that horns play differently for different players, I'd still be interested in hearing about the differences between the B7 and the 8310Z by someone who has played on both. Anyone out there who can help?
