In the course of my life as a woodwind technician, I come across many student instruments manufactured by companies other than the ones I grew up with. That's not necessarily a bad thing, because when these instruments are new and properly regulated, they play OK. The problem I see is that they have a tendency to go out of adjustment very easily. The keywork is generally not as sturdy as your 1969 Bundy Resonite Clarinet, so it can bend very easily. The metal is cheap and the tolerances aren't exact enough. If you are a typical fifth grader trying to assemble and use one of these budget instruments on a regular basis, bad things are likely to happen. Students end up working a lot harder to get keys to operate properly and produce a quality tone. Look, it's hard enough to play an instrument well in the first place. Why make it more difficult by saddling these kids with inferior equipment?
So, if you are planning to purchase a new instrument for your aspiring musician, be sure to have a professional check out your purchase before you buy. There are numerous used beginner instruments available which may need some work, but will serve your needs. Very well. You'll save some money in the long run and your young musician will have greater success from the outset. And if you need an instrument serviced, please contact me at Robert Chadwick Woodwind Repair.
