Production The company is notable for making saxophones from materials other than the standard brass (i.e., phosphor bronze and solid silver, and combinations thereof). Their first solid silver saxophone was produced in 1972 and instruments made from phosphor bronze began to be produced in 1992. The 8830 model alto and tenor saxophones, introduced in 1988, combined silver necks and bells with a brass body tube, reminiscent of the King "Silversonic" instruments. Similar combinations are offered in current production, as illustrated by Yanagisawa's 2015 range of alto saxophone offerings: AWO1 - made entirely from solid brass.
