I'm slowly learning to play my Rochelle anglo, and having a blast, but as I've expanded the set of notes I'm using, I'm noticing a few that don't play cleanly. I've heard mention of buzzing reeds, and I'm not sure if this is that, but in addition to the note, I get secondary sound that's sort of...I guess I'd describe it as kind of an air-y sound, but with a bit of texture to it, like sucking through a straw in a just-about-empty glass. It only seems to happen in one direction - that is, on the draw for the F, but not the push for the G, and likewise the push for the E, but not the draw for the D. It also seems to be more noticeable if I have the relevant end of the instrument at a tilt, as opposed to perpendicular to the ground.
Any ideas? And if so, is it something that I could even remotely conceive of looking at myself (I wouldn't consider myself particularly handy with tools), or should I just live with it (it's not too bad, and doesn't stop me enjoying playing) until I upgrade to a better instrument? There is also the shop where I got it from, but it's a non-trivial drive, and has inconvenient hours for me.
