Replacement Tuning Machine Knobs

GoldBug replacement tuner knobs are a stunning enhancement to any guitar or other fretted instrument.

The ornamental designs used on GoldBug hardware are based on classic designs found on such items as historic firearms and jewelry as well as antiquarian books and manuscripts. These designs are then modified and hand sculpted in our studio. These sculpted and engraved designs will lend an understated elegance to any instrument that will transform it into a treasured personal statement.

Any musician will be proud to upgrade his or her instrument with these fine examples of masterful craftsmanship and artistry.

GoldBug replacement tuning machine knobs are designed to fit on Grover, Schaller, Ping and Gotoh tuning machines.* Click here for installation instructions.
