Wo, Michael! I'm impressed. Really. I spent a bunch of years as an high school English teacher and, after reading that you're 17 years old and, if I understand correctly, writing in a second language, well, I was totally caught up in how well you expressed yourself. Your assessment of these three instruments sounds like that of a mature-minded person (which many teenagers are). And your use of the English language is very real and conversational, yet uses technical jargon very naturally.

I don't mean to sound like a teacher or anything, but, Michael, you write in your own voice and I'm hearing you loud and clear. I look forward to future posts.
