Schaller M6 Large Metal Chrome Guitar Tuning Machines

Replacement Tuning Knob for Schaller M6 Series

This replacement button fits Schaller M6 and M6 Mini closed-gear machine heads. It drops onto the standard 4.2 mm bore of the M6 shaft, so a worn or lost knob can be swapped in minutes without disturbing the rest of the tuner. Machined from solid metal with a Chrome finish, it weighs 9 g and gives the headstock a slightly heavier feel than plastic or pearl buttons.

What to check before buying

Confirm the instrument uses an M6 or M6 Mini tuner — the 4.2 mm bore is specific to this series. The button ships without a mounting screw, so the original screw from the old button is reused. Chrome matches other Chrome hardware; the same button is also available in Nickel, Black, Gold and Ruthenium for colour-matching or contrast.
