I have been playing for the last 2 years a Yamaha 34 that is in tune and has reliable keywork. But I bought a Thibouville Freres last week that has a fat sweet tone. Problem is its not nearly as in tune as the Yamaha. My teacher seems to think its not worth the bother and I sound okay on the Yamaha. What happens for me is I play a slow scale on this Thibourville and say to myself, see, my tone is as good as what I hear on classical records. So, I don't know whether I should deal with the intonation or just go back to the Yamaha and try to fatten that up? I felt like I took Dr Gs advice but my teacher just shakes her head. (she sound beautiful on a Buffet Greenline but I can't spend that kind of money. ) K
