Here is a little secret.
Göldo´s owns the Kluson rights to use the name in Europe, WD Music owns the right in the US.
Here is another secret. These tuners are in fact Gotoh SD91. And Gotoh makes the best vintage style tuners out there right now. (they are stamped "japan")
Since Gotoh can not use the Kluson single/double on their Tuners, Göldo can. So these are best of both worlds. Branded tuners by Gotoh/Kluson.
You will not get all the customisation with these that Gotoh offers, but for vintage correct tuners, these are the closest you can get to real deal.
