I'm interested in getting a bass trumpet, but I don't know much about them. Basically I'm looking for some variety - I play a Bach Stradivarious model 37 that I've had for 30+ years and I love it. But I don't have the upper range I used to (hence the idea of trying a lower range instrument). I play mostly jazz. I've heard a bass trumpet just once and liked the sound. When I look locally I can only find shops willing to order me a new horn for over $2,000 - no one ever seems to run avross a used one. EBay occasionally has something used but I can't really tell what I'd be getting. I'd welcome anything anyone can tell me - how to select one, where to find one, whether this is a bad idea. Thanks!
