Not to discourage you from upgrading, but one of my bandmates buys those cheap Chinese sopranos all the time. When one breaks, he just buys another. He is an excellent player and sounds fantastic on them, in spite of the fact they're terrible horns. But he likes all the weird colors and designs and the fact he doesn't have to worry about how he treats them.
This is how I’ve always felt. The Chinese sopranos at that price point are almost disposable.
I own an Antigua Winds student model alto that I thought was the best horn ever…until I bought a Pan American stencil, which was a major upgrade for me as far as intonation, weight and ease of pay. I discovered while playing the Pan American that I prefer the warmer tone. Now the AW seems too heavy and too bright. I later got a good deal on a Yamaha YAS-23, thinking it would be as special as my YTS-52 tenor but I hate it. That Pan American is the best I’ve ever played. I discovered that by trying something else although I was pleased at the time with the AW.
I want to pick up another soprano to see if my Chinese horn is really not as special as I think it is. I’m learning “Dienda” by ear and the higher notes I’m finding are difficult. Not sure if it’s the horn or my own playing limits. A good friend of mine played my soprano and made it sing, so it’s probably me. I’m pleased with the sound it produces for me, but of course, as a Beginner, I don’t have much of an ear yet. To a trained ear it could sound like a cat being drowned so I’m curious about other horns.
Thanks everyone for the suggestions!
