This is one of those questions I should probably apologize for in advance: I'm new to the trumpet (sax player) and playing for maybe two months now. I have a Gtezen Severinsen Eterna from the early 70s in great shape that I had serviced by a professional tech. Recently, I picked up a 1952 Blessing Standard from a guy on Craigslist for $50. It's in nice shape too. Anyway, using the same mouthpiece (Bach Artisan 5C) I find it easier to play the Blessing than the Getzen. I can't describe it like you guys can, but it just blows more easily for me. Maybe it's my imagination. I'm hoping someone knows these horns well enough to offer a possible explanation. Thanks!
