I ordered these tuning machines to replace the stock tuners on a Hofner Ignition Club Bass, since the original felt really cheap and clumsy. These are supposed to be the ones that go on the expensive German Hofner basses, and even they still look like guitar tuners with a plain open mechanism, they are well made and feel smooth and steady.
It's worth noting that they come with bushings and mounting screws, as a set (I was not sure because it is not mentioned in the product description).
Keep in mind though that it is not a direct replacement for an Ignition bass: some minor work has to be done in order to accomodate these tuners. The bushings are slightly larger in diameter, so the holes on the Ignition headstock need to be widened (about 1mm). Then, one of the mounting screws fits one of the existing holes, but for the other screw it's necessary to drill a new guide hole.
