Blown reeds are a bit of a mystery to me. While playing, there are almost always two or more buttons depressed, often enough as many as five if you count the bass side. I'm not sure how hard you would need to press to blow a reed, but it must be hard indeed. I guess I will know if I ever do blow one. I have to admit my 10 year old LeCapitaine is a touch leaky (hang it by the bass strap and it will stretch out in about a minute and a half), but I think that just makes it more playable. I always strive to smile and play in an easy relaxed manner, if you do that, your arms will not get tired and there is probably no danger of blowing out a reed.
