Does anyone else think it's weird that it's impossible to find Grayhills in the US, when they're based in Illinois??? Illinois, Wisconsin and CHINA (<--- haha, of course) according to their website. It's just irritating that they're so hard to locate, and I'm from Missouri!
have you guys tried calling them? You could just order direct. Shorting switches are going to be hard to find unless you find some high end audio diy shop or something.
