Well, I was playing around on der intarweb today and came across the flyer for the Yamaha YCL-CSG-H custom clarinet. Here's an excerpt: "The YCL-CSG-H is the same clarinet [as the YCL-CSG] but with a Hamilton plate finish on the keys. Hamilton plating consists of gold with some nickel and copper added. Many players find it darkens the sound while at the same time giving tonal clarity and projection. They feel it also helps create a creamy smooth texture to both the sound and the response." I've never read such BS. Although I'm sure some player can try to convince you that havening gold plated keys that aren't even over a tonehole will affect the tone, I'd say 99 and 44th/100 of us will say, "Gee, the gold-plated keywork just looks nice." If you're wondering, on WWBW.com, the silver-plated keyed version costs $2579 and the Hamilton gold costs $2804. Hey, $225 for almost gold keywork? That's probably worth it, but just don't try to convince me that the keywork is impacting the tone.
