My Selmer Series III is having problems. I've had it for approx. 7 months. It's been in for repairs five times for the same problem- innumerable leaks. And it keeps coming back moderately better, but not fixed. It's nearly impossible to play softly or in the low register. Even my teacher, who's a professional player and a college professor, can't get it to play correctly.
After this much trouble, what would you do? It's still under warranty, and I'm honestly thinking about demanding a replacement. My teacher thinks the keyholes may be uneven.
