I hate to ask a stupid question, but who manufactures Gotoh hardware? I would like to assume that its a company called Gotoh but I'll be damned if I can find any company info or a website of any kind.
When a company chooses to deal only as a supplier to manufacturers, its not uncommon for their web presence to be sparse or even no web presence. They cater to the likes of Gibson, Fender, Taylor, PRS, and so on down the chain. Gotoh has "some" web presence. Try finding Ping on the web. Ping supplies more tuners (and other hardware) than just about anybody.
