A few years back I switched to Yanagisawa. Out on the web they are considered one of the big 4 (Sel, Yam, Keil being the others).
I began to have big problems with my Super Action 80, and didn't like the tone I produced on serie II & III.
When I first got my A991 alto, I can say that I didn't like it. It is extremely heavy built. I learned that it wanted to be driven hard like a sports car. It has an incredible tone at volume and projects more than any horn I've owned. I now can play it cleanly even at subtone levels, but it took time.
The one really cool thing out of the box was the intonation. I put it on the tuner and nailed virtually the entire scale of the horn. I'm not a great 'in-tune' guy...so that was big for me.
Anyway, I've since added and S-902 bronze soprano and T-901 tenor to the arsenal. They are without question the horns for me. I'm not doggin Selmer or anyone else as horns (and our relationships with them) are a very personal thing.
If anyone has questions about Yanagisawa please let me know.
Thanks,
