My new custom mandolin arrived with StewMac tuners that I hated from the moment I opened the box, so I had to source alternatives. After a lot of deliberation I went upmarket, and ordered new ones from Keith Robson Tuning Machines in England. (That link goes to his Facebook page; his new website is under construction and won't go live until the beginning of December).
Fitting them was relatively straightforward, although it did require the filling and re-drilling of four screw holes, which was a little daunting. The tuning post spacing is the standard 23mm, and the tuners (and their very sweet bushings) went into place with next to no work required.
Keith was a delight to work with, answering my many questions promptly and informatively. His tuners are beautifully crafted, high-end items that have transformed the instrument which, with the original tuners, was painfully difficult to tune and almost impossible to keep in tune. Highly recommended.
