Gold epoxy lacquer Microscopic, electrically-charged particles of lacquer are attracted to and deposited evenly on the surface of the instrument carrying the opposite charge. This produces an exceptionally thin, uniform coating that can be oven-hardened for maximum durability without compromising the instrument's sound. The sound produced is a solid, somewhat harder sound than silver plate finishes.
Gold brass leadpipe Gold brass is extremely resistant to wear and corrosion, and when used in a leadpipe, it ensures long-term precision.
