Independent shopping perspective
Black, non-collared 3-per-side Revolution machines for guitars that match the vintage Kluson footprint, mounting pattern, and 11/32-inch peg holes. Their sealed zinc housings keep the gears enclosed, with a 19:1 ratio for controlled tuning changes. After tuning, the locking mechanism secures the posts. Included push-in bushings support friction-fit installation, and the metal keystone buttons with pinstriping retain the familiar Kluson-style outline.
