Schaller’s new Da Vinci tuning machines use a redesigned worm gear the company says offers the precision normally associated with enclosed/greased machine heads, and has a “window” made of scratch-proof UV-resistant polycarbonate. They’re available in a variety of finishes, including 24K Fold, Nickel, Ruthenium, Chrome, SatinPearl, BlackChrome, SatinChrome, and VintageCopper. See more at schaller-electronic.com.
