This interests me, as I get to know various instruments I find that brands have their own sound, especially in their better instruments. My excelsior 940 has that mellow round "jazz" sound, without much brightness or edge to it, a Guerrini Superior I owned years ago was brighter, more complex but maybe a bit thinner in tone, the Titano/Victoria I have has a rich tone, not as mellow as the Excelsior, more colourful and dynamic to my ear. Anyways, I'm curious about other people's impressions of various brands' sounds. On a continuum from super mellow to bright, where do they fall? Or from pure tones to complex?
