My e string tuner gears stripped and was told that Schaller in their early days used guitar tuners and partially modified them for basses and where prone to stripping. According to a tech at Hipshot Products, who modified my e tuner to a drop d, the Schaller M4 has the same internals (also prone to stripping?). The holding pin is in a different location also than the originals. The Schaller M4 2000 angle 90 degree model appears to be the same as the original tuners and the distance measurement to the holding pin seems the same. Has anyone used any of the latest model tuners, for the 450B in particular, from Schaller with success? Thanks for any replies or suggestions.
