"Simply the best you can get." — David Grisman Our uncompromising design features patented threaded worm tension bushings that eliminate looseness, for maximum tuning efficiency. The precision-machined stainless steel worm gears, bronze alloy string post gears and 16:1 gear ratio assure smooth, accurate tuning. Performing artists stay in tune with Waverly: “The best tuners in the world.” — Chris Thile “They have changed my life.” — Sam Bush "I love Waverly tuners. The keys move with ease and hold strong, two important qualities we must have to perform night after night. I have Waverly tuners on all my mandolins." — Rhonda Vincent Ultra-smooth operation, precise, reliable tuning, long life and classic beauty. Each handsome engraved baseplate is now computer-machined from a single brass billet, for lighter weight with unwavering stability. Standard spacing measures 29/32" (0.906") between each string post. String post diameter: 0.236" Required peghole diameter: 21/64 or 0.328" Each set includes: • Pair of 4-left, 4-right tuning machines • Knurled press-fit brass peghead bushings • Mounting screws Installation Tips Peghole spacing: Plate-mounted tuners can't work efficiently if the pegholes are improperly drilled. These tuners require precise 29/32" spacing for accurate alignment. Bushings: Get the right fit! Use a slow-speed 0.328"-diameter reamer to cut a clean, accurate counterbore for a professional job. Mounting screws: Pilot holes required. Installing delicate screws into hard wood requires great care and accuracy. We highly recommend a 5/64" bit for the pilot hole before installing these screws. Lubricate the screw threads with cutting lubricant (also wax or a bar of soap) to reduce friction and help them thread properly.
