For slotted steel-string guitars Our precision plate-style 16:1 machines feature the same gears and patented threaded worm bushings found on all Waverly guitar machines, for maximum tuning efficiency. 1/4"-diameter brass string shafts with 35mm/1-3/8" spacing are mounted on cast polished bronze baseplates. These artistically engraved plates age to a handsome patina. Slotted, round-head mounting screws included. Made in USA
