Mechanically, this is the same horn as the Yanagisawa 901. The differences is that this horn is made entirely of bronze, not brass. This alloy, which Yanagisawa includes on their top-of-the-line instrument, the 992, adds more depth and sonic resonance to this already superb instrument. The extra power that is felt from behind this solid bronze instrument gives the player a significant edge over his colleagues playing standard brass instruments. This horns has the awesome sonic qualities of the 992 with a price tag those on a budget can be more comfortable with.
